Description
Technical field
The present invention relates to integrated circuit fields, or rather, relate to storer.
Background technology
Prerecording memory device (pre-recorded memory) is meant the storer that the information of depositing has been written into before the user buys.It is particularly suitable for the distribution of copyrighted data (being data protected by copyright), as multimedia file, e-book, recreation, software, GPS map, electronic dictionary etc.Prerecording memory device can use various nonvolatile memories (non-volatile memory, be NVM), as masked edit program storer (mask-ROM), write primary memory (one-time programmable, be OTP), write repeatedly storer (write-many, be WM, as flash memory).
Shown in Figure 1A, in the prior art, the finite capacity of each memory chip (as 22D), it can only store a small amount of data (as file 28d).In order to meet consumers' demand for 20 (comprising file 28a, 28d, 28e etc.), prerecording memory device often needs to use a plurality of chips (22A, 22D, 22E etc.).
Shown in Figure 1B, along with the progress of integrated circuit technique, the capacity 23 of prerecording memory device chip sharply increases.Compare gather way slow (because progress of compress technique etc.) of user's request 20 with it.When the A point, only need (or a small amount of) chip just can meet consumers' demand 20.
Shown in Fig. 1 C, along with the further raising (being the A point back of Figure 1B) of chip-stored amount 23, the capacity of a prerecording memory device chip 24 can also satisfy most users' demand greatly to the demand 20 that can not only satisfy certain specific user.Three-dimensional storage (three-dimensional memory, i.e. 3D-M is referring to Chinese patent ZL98119572.5) comes to this a kind of storer.Estimate that the capacity of a three-dimensional memory chip can reach 4GB after 3 years, this is equivalent to 1000 first MP3 songs.(or a small amount of) three-dimensional memory chip just can satisfy most users' basic music demand.
Prerecording memory device is fit to the storage copyrighted data.When the memory space of chip 24 greatly during the situation in Fig. 1 C, can store a large amount of copyrighted datas on each chip 24, the copyright royalty of these data is surprising! This chip will become so, and very expensive (copyright royalty will be far above the chip expense if the user can unrestrictedly visit these copyrighted datas! ).In fact, each user only can be interested in part information (as file 28a, 28d, 28e) wherein, and other data (as file 28b, 28c, 28f etc.) is lost interest in.In all conscience, the user only should be his interested data (as file 28a, file 28d etc.) and pays copyright royalty.Correspondingly, the present invention proposes a kind of user control pre-recorded storer (user-configurable pre-recordedmemory abbreviates UC-PM as).In UC-PM, the user can select his interested data, and only need pay the copyright royalty of these data.
Goal of the invention
Fundamental purpose of the present invention provide a kind of user can own selection he the prerecording memory device of data interested.
Another object of the present invention provide a kind of user only need pay he the prerecording memory device of copyright royalty of data interested.
Another object of the present invention provides a kind of to the copyright holder with fair per family copyrighted data distribution pattern.
According to these and other purpose, the invention provides a kind of user control pre-recorded storer (UC-PM).
Summary of the invention
Along with the increase sharp of memory span, a prerecording memory device chip can be stored a large amount of copyrighted datas.The copyright royalty of these data is surprising! Very natural, the user does not wish to be his uninterested data payment copyright royalty.Correspondingly, the present invention proposes a kind of user control pre-recorded storer (being UC-PM).In UC-PM, the user can select his interested data, and only need pay the copyright royalty of these data.With music UC-PM (UC-PM that promptly has music information) is example: in the music UC-PM that has just sold, the user only has limited access right (as can only the audition every first song of user several times) to music information; When user's decision will have a first song, he bought corresponding fetcher code from the copyright holder; In case this fetcher code is input among the UC-PM, the user promptly obtains the access right of this head song.
Three-dimensional storage (especially masked edit program 3 D ROM, i.e. 3D-MPM) has the capacity of super large and cheap price, is the desirable memory bank of prerecording data.The more important thing is that its substrate can be used for forming access control circuit.Prerecording data and access control circuit are integrated in the chip like this, thereby make the bootlegger be difficult to steal the data of storage.Therefore, three-dimensional storage especially is suitable as UC-PM.If again decipher (decryption engine), demoder (decoder) and digital to analog converter (ADC) are designed in the substrate of three-dimensional storage; this UC-PM chip based on three-dimensional storage (3D-M UC-PM) will provide control of extremely strong access rights and copyright protection (referring to United States Patent (USP) 6 to its data of depositing so; 717,222).
UC-PM (especially 3D-M UC-PM) will cause a kind of distribution pattern brand-new, copyrighted data.Because UC-PM provides control of extremely strong access rights and copyright protection for its data of depositing, its price can be extremely low, or even can free of cost; Its hardware cost can be bought the copyright royalty that its data pays by the user and reclaim.Compare with it, only provide limited access rights control and copyright protection based on the prerecording memory device of CD, flash memory etc., they can not adopt this mode to issue copyrighted data.The user must pay the copyright royalty (even he uninterested data) of all data when buying.This distribution pattern causes multimedia document to cost an arm and a leg, and is difficult for accepting extensively for the user.
UC-PM can also combine a kind of data memory of formation with user's recording and storing device (as flash memory).In this data memory, UC-PM stores most of user's interest data, and user's recording and storing device is stored the interested data of this individual subscriber.This data memory merges the dirigibility of low cost, high capacity and the user's recording and storing device of UC-PM, thereby reduces the carrying cost of data.
The present invention also provides two kinds of improved storeies based on diode: narrow linewidth diode memory and wide word line diode memory.In the narrow linewidth diode memory, the characteristic dimension f of diode can be much smaller than transistorized characteristic dimension F.This is because the transistorized replacement is subjected to multiple effects limit (leaking design etc. as photoetching, grid material, gate insulation layer material, source), and much less is wanted in the suffered restriction (generally only being photoetching) of the replacement of diode, so diode can be regenerated with fast speeds.The narrow linewidth diode memory is suitable for three-dimensional storage (being particularly suitable for the masked edit program 3 D ROM, i.e. 3D-MPM).This is because transistor is in different circuit layers with diode: transistor is in the substrate, and diode is in the accumulation layer on the substrate.They are independently formed by different processing steps, and transistor can adopt different technology respectively with diode like this.
In wide word line diode memory, especially in the three-dimensional storage, the word line live width is more preferably greater than the bit line live width.This be because: 1) yield rate of diode memory is to word line defect comparatively responsive (the bit line defective is more easily corrected); 2) in read procedure, word line provides electric current need for many bit lines, and its square resistance preferably has smaller value.

Embodiment
The present invention proposes a kind of user control pre-recorded storer (user-configurable pre-recordedmemory abbreviates UC-PM as).In UC-PM, the user can select his interested data, and only need pay the copyright royalty of these data.With music UC-PM (UC-PM that promptly has music information) is example: in the music UC-PM that has just sold, the user only has limited access right (as can only the audition every first song of user several times) to music information; When user's decision will have a first song, he bought corresponding fetcher code from the copyright holder; In case this fetcher code is input among the UC-PM, the user promptly obtains the access right of this head song.
Fig. 2 A-Fig. 2 B represents the use pattern of two kinds of UC-PM.In this embodiment, UC-PM88 is a music UC-PM, and has a large amount of copyrighted music data.In Fig. 2 A, the beginning user can not listen music information (step 31) wherein.In input reference code 33 back (step 34), the user just can listen the music information (step 32) corresponding with this code 33.
The embodiment of Fig. 2 B has an audition stage.In this audition stage, the music of user in can audition UC-PM88 n time, or audition a period of time (step 35).After this audition stage, the user no longer includes access right (step 36).In input reference code 38 back (step 39), the user can listen music information N time (step 37) corresponding with this code 33.Here, different fetcher codes 38 can allow the user that different access rights are arranged.As user's input reference code A, then he can listen 5 times (N=5) of certain first song; As input reference code B, then he can listen this first song infinite time (N is for infinitely great) (referring to Fig. 5 A).
Fig. 3 A is the circuit block diagram of a kind of UC-PM 88.It contains a memory number 18, a prerecording memory device 00 and an access control block (ACB) 10.Memory number 18 is to be used for discerning this UC-PM 88 unique codes, and it needs to use (referring to Fig. 9 B) under situations such as purchase fetcher code.The data of prerecording memory device 00 storage prerecording.It contains as lower port: address 06, read to enable 02, output 04 etc.Access control block (ACB) 10 controls are to the visit of these prerecording data.Shown in Fig. 3 B, it further contains tag block 12, label monitoring piece 14 and label piece 16 is set.Tag block 12 has the label of each file.Label value is the visit information of file, as last addressable number of times.Here, label 40a is corresponding to file 28a, and label 40b is corresponding to file 28b....According to file pointer 50, can from prerecording memory device 00, read corresponding file (as 28a), from tag block 12, read corresponding label value (as 40a) simultaneously.Label monitoring piece 14 is read enable signal 52 based on label value (as 40a) output one: when 52 sets, the output 56 of prerecording memory device 00 is the file of being read (as 28a); When 52 resets, 56 no-outputs.Label is provided with piece 16 and according to the fetcher code 54 that the user imports label value is set.
UC-PM88 has two kinds of mode of operations: data readout mode and label are provided with pattern.In the data readout mode, the user reads the file (Fig. 4 A-Fig. 4 B) that he has access right; Be provided with in the pattern at label, user's input reference code is to change his access right (Fig. 5 A-Fig. 5 B) to corresponding document.
Fig. 4 A represents first kind of sensing circuit of UC-PM, and it is corresponding to first kind of use pattern among Fig. 2 A.According to file pointer 50, can from prerecording memory device 00, read corresponding file (as 28a), from tag block 12, read corresponding label value (as 40a) simultaneously.In this embodiment, label only contains a tag bits: if this tag bits (as 40a) is " 1 ", then can visit corresponding file (as 28a); Otherwise can not.In readout, label value is at first read, and is used as and reads enable signal 52 and directly deliver to storer 00, whether reads corresponding file (as 28a) with decision.
In this embodiment, in a single day tag bits is set up, and just need not change.Therefore, tag block 12 can be used write primary memory.A kind of write primary memory of first-selection is XPM storer (referring to United States Patent (USP) 6,777,757).Because XPM storer and standard CMOS circuitry compatibility do not need to improve technology,, and be easy to realize so it is cheap.Another kind of first-selected write primary memory is electric programmed three-D ROM (read-only memory) (being 3D-EPROM, referring to Chinese patent ZL98119572.5), and it also is easy to integrate with prerecording memory device etc.
Fig. 4 B represents second kind of sensing circuit of UC-PM, and it is corresponding to second kind of use pattern among Fig. 2 B.Different with Fig. 4 A is that label value is last addressable number of times.The label of this embodiment contains 8.For example, the label value of 42a " 05h " expression also has remaining access times 5 times to file 28a; The label value of 42b " 00h " expression can not be visited file 28b; The label value of 42c " FFh " expression can unrestrictedly be visited file 28e.
In readout, label value is at first read.If output 12o＞" 00h ", then the output 52 of label monitoring piece 14 is " 1 ", and corresponding file is read out in the storer 00; Otherwise, do not have file to be read out.Label monitoring piece 14 can also upgrade label after each read operation.When " 00h "＜12o＜" FFh ", label monitoring piece 14 falls 1 with the value of 12o, promptly 12i (12i=12o-1) is write back tag block 12; Under other situation (as 12o=" 00h " or " FFh "), label monitoring piece 14 does not upgrade label.Because label will upgrade, this tag block 12 needs to use writes repeatedly storer.
Fig. 5 A represents that first kind of label of UC-PM is provided with piece 16, and it is provided with according to 54 pairs of tag block 12 of fetcher code of user's input.Label is provided with piece 16 and contains a code conversion table 80, and this code conversion table 80 is set up one by one corresponding between fetcher code and accessed file and addressable number of times thereof.It contains a plurality of clauses and subclauses 70, and each clauses and subclauses 70 contains fetcher code 72, file pointer 74 and addressable number of times 76.For example, " code 0A " expression permission is the file access 5 times (" 05h ") of 000h to file pointer; It is the file access 15 times (" 0Fh ") of 000h that " code 0B " expression allows file pointer; It is the file access unlimited (" FFh ") (here, " FFh " singly refers to unrestricted number of times) of 000h that " code 0C " expression allows file pointer.
In order to protect copyright, for identical file and addressable number of times, different user (being different memory number 18) should have different fetcher codes.Therefore, code conversion table 80 should make the electricity consumption programmable memory.Because code conversion table 80 is written into before the user buys, need not change after the purchase, this electricity programmable memory can be a write primary memory, as the XPM storer or the 3D-EPROM of Fig. 4 A use.
Behind user's input reference code 54, label is provided with 16 pairs of code conversion tables 80 of piece and searches by address 70.If the output 72o of code conversion table 80 is identical with the fetcher code 54 of input, signal 72c set, and be sent to tag block 12 write Enable Pin 12w.Like this, be the address with file pointer 74o, addressable number of times 76o is written into tag block 12.
Fig. 5 B represents that second kind of label of UC-PM is provided with piece 16, and it is calculated file pointer 74o and addressable number of times 76o by a kind of algorithm from fetcher code 54 and memory number 18, that is:
File pointer 74o=function A (fetcher code 54, memory number 18) (1)
Addressable number of times 76o=function B (fetcher code 54, memory number 18) (2)
This algorithm can be realized by a hardware 78.Notice that 78 also have an output 78o.When the fetcher code 54 of input when being valid code, 78o set, and be sent to tag block 12 write Enable Pin 12w.Like this, be the address with 74o, 76o is written into tag block 12.When 54 are invalid code, the 78o reset, 12 can not write data.
Fig. 6 represents a kind of UC-PM 88 that is made of the Stand Alone Memory chip, and it contains two prerecording memory device chip 62a, 62b, and an access control chip 64.Prerecording memory device chip 62a, 62b have the data of prerecording, and access control chip 64 plays the function of access control block (ACB) 10.Because the bootlegger can directly steal copyrighted data from 62a, 62b, the copyright protection of this embodiment haves much room for improvement.
Fig. 7 is the sectional view of a kind of three-dimensional storage (being 3D-M, referring to Chinese patent ZL98119572.5).This embodiment contains two accumulation layers (100,200), and they are mutually stacked and be stacked on the substrate 0.Many address selection lines (comprising word line 120,220... and bit line 130,131,230,231) and a plurality of storage element (140,240...) are arranged on each accumulation layer (as 100).Accumulation layer 100 realizes being electrically connected by interlayer interface channel hole 120v and substrate circuitry 90.Three-dimensional storage can be electric programmed three-D memory (is EP-3DM, as writes three-dimensional storage, write repeatedly three-dimensional storage), also can be non-electric programmed three-D memory (being NEP-3DM, as masked edit program 3 D ROM, i.e. 3D-MPM).This embodiment is a 3D-MPM: it represents " 0 " or " 1 " with whether existing of spacer medium 153,253: as storage element 140 expressions " 0 ", and storage element 240 expressions " 1 ".
Because three-dimensional storage has the capacity of super large and cheap price, it is the desirable memory bank of prerecording data.The more important thing is that because three-dimensional storage 00 (especially 3D-MPM) does not account for Substrate Area 0 (except its peripheral circuit 92) substantially, its substrate can be used for forming various substrate circuitry 0SC, with copyright protection and the access rights control of strengthening the prerecording data.Correspondingly, the UC-PM chip based on three-dimensional storage is called as 3D-M UC-PM chip.Fig. 8 A-Fig. 8 C represents several 3D-M UC-PM chips.
In the 3D-M of Fig. 8 A UC-PM chip, substrate integrated circuit 0SC contains access control block (ACB) 10.Because access control block (ACB) 10 is integrated in three-dimensional storage array 00 time, it is extremely difficult monitored, so this embodiment has passed through good access rights control for copyrighted data.
Because but 3D-MPM has fabulous integration, it is the first-selected storer of UC-PM.In order to prevent that the bootlegger from utilizing anti-design of 3D-MPM spacer medium figure (as 153,253) to obtain data information, preferably its deposit data is encrypted, promptly the data of spacer medium figure representative are encrypted.Correspondingly, in the embodiment of Fig. 8 B, substrate circuitry 0SC also contains a decipher 82, and it is reduced into raw data 83 with enciphered data 81 deciphering of reading among the 3D-MPM 00.Substrate circuitry 0SC also contains access control block (ACB) 10, and its control is to the visit of each file.Because decipher 82 and access control block (ACB) 10 all are integrated in three-dimensional storage array 00 time, they are extremely difficult monitored, so this embodiment provides copyright protection and access rights control preferably for copyrighted data.
The misgivings of another copyright protection are that the bootlegger can steal copyrighted data by the numeral output (as the signal among Fig. 8 B 85) of monitoring UC-PM.At this misgivings, the multimedia of UC-PM output (as audio-video signal) is simulating signal preferably.Even the bootlegger can be with the digitizing again of these simulating signals, its quality of signals can greatly reduce.
Fig. 8 C provides a kind of embodiment that adopts above method protection copyright.The decipher 82 and access control block (ACB) 10 in last figure, its substrate circuitry 0SC also contains a demoder 84 and digital to analog converter (DAC) 86.84 pairs of prerecording information of demoder (generally being packed data) decompress, and its example comprises audio decoder (as the MP3 decoding device) and Video Decoder (as jpeg decoder, mpeg decoder).Digital to analog converter 86 changes into simulating signal 89 with these decoded signals 87.Simulating signal 89 can be a simulating signal (as voltage swing) in general sense, can also be PWM (pulse-width modulation) or PPM signals such as (pulse-position modulation).Because demoder 84 and digital to analog converter 86 all are integrated in three-dimensional storage array 00 time, they are extremely difficult monitored, so this embodiment provides almost optimal copyright protection and access rights control for copyrighted data.This chip is had boundless prospects.
The present invention also provides a kind of distribution pattern-UC-PM pattern of copyrighted data.Shown in Fig. 9 A, (especially based on 3D-MPM UC-PM) provides extremely strong copyright protection to copyrighted data because UC-PM, and its hardware price can be extremely low, even free of cost (step 71).The user can try out these information papers (step 73).If he is satisfied with (step 75), then buy corresponding information paper (step 77), producer then regains hardware cost by the data copyright royalty of user's payment.Compare with it, only provide limited access rights control and copyright protection based on the prerecording memory device of CD, flash memory etc., they can not adopt this mode to issue copyrighted data.The user must pay the copyright royalty (even he uninterested data) of all data when buying.This distribution pattern causes multimedia document to cost an arm and a leg, and is difficult for accepting extensively for the user.Generally speaking, the UC-PM pattern is more fair concerning copyright holder and user.
Fig. 9 B represents that user 61 buys a method of fetcher code 54 from copyright holder 63.When user 61 wished to obtain the access right of a file, he was provided with equipment (as computing machine) with UC-PM and and links to each other.This is provided with equipment and reads its memory number 18, and shows the tabulation of the file of depositing, and the various addressable number of times of each file.The user selects its required file and addressable number of times, and sends these information (as memory number 18, file pointer 41 and addressable number of times 43) and payment information to copyright holder 63 by the Internet or phone 67.On the other hand, copyright holder 63 grasps an access code data storehouse 65 is arranged.This database 65 can obtain corresponding fetcher code 54 by mode or a kind of special algorithm of table look-up (look-up table).Here, fetcher code 54 is functions of memory number 18, file pointer 41, addressable number of times 43:
Figure 10 represents a kind of data memory 84 with UC- PM 88 and 86 combinations of user's recording and storing device.The Gu Mingsi meaning, user's recording and storing device 86 can be changed the data of its storage by the user, and it is generally writes repeatedly storer, as flash memory.In this data memory 84, the most of user's interest data of UC-PM 88 storages, the interested data of user's recording and storing device 86 these individual subscribers of storage.This data memory 84 merges the dirigibility of low cost, high capacity and the user's recording and storing device 86 of UC-PM 88, thereby reduces the carrying cost of data.
In integrated circuit technique, the transistorized replacement is subjected to multiple effects limit, leaks design etc. as photoetching, grid material, gate insulation layer material, source.On the other hand, much less is wanted in the suffered restriction of the replacement of diode, and it is only by photolithographic constraints in general.Correspondingly, the replacement of diode memory is followed different rules with the replacement of transistor integrated circuit:
1) the characteristic length f of diode (being the semiperiod half-pitch of address selection line among Figure 11 A) is littler than transistorized characteristic length F (being the semiperiod of polysilicon gate among Figure 11 A).Can use the technology of f=60nm as diode memory, and transistorized memory still need use the technology of F=90nm;
2) replacement period ratio transistor of diode is short.For example say that diode memory needed 2 years to change a generation, transistorized memory need change a generation in 3 years.
All things considered, diode memory will be bigger than transistorized memory capacity, and the gap between them can be increasing.
Except forming in substrate together with transistor, diode memory can be integrated in substrate (containing transistor) top in the mode of three-dimensional storage.In three-dimensional storage, (be positioned at Figure 11 A substrate 0 li) is in different circuit layers with diode 140,141 (being positioned at substrate 0 top) because transistor 0T1,0T2, they are independently formed by different processing steps, and transistor can adopt different technology respectively with diode like this.Correspondingly, the present invention proposes a kind of narrow line three-dimensional memory.
Figure 11 A-Figure 11 B is a kind of sectional view and top view of narrow line three-dimensional memory.Its accumulation layer 100 contains a plurality of storage elements 140,141 (and spacer medium 153), word line 120 and bit line 130,131.Its substrate contains an integrated circuit 0M (comprising transistor 0T1,0T2).The characteristic dimension f of three-dimensional storage diode is 130,131 minimum period of address selection line (pitch) P2 (=2f) half; The characteristic dimension F of substrate transistor is for there being effect transistor (referring to have the transistor of certain function) 0T1,0T2 grid 1p1,1p2 minimum period P1 (=2F) half.In this embodiment, all substrate circuitry are all according to the F technological design; All accumulation layers are all according to the f technological design.Because f is less than F, so this kind three-dimensional storage is called as narrow line three-dimensional memory.Because the storage element of masked edit program 3 D ROM (being 3D-MPM) only contains diode, its structure is the simplest, so narrow line three-dimensional memory especially is fit to 3D-MPM.
The interface channel hole 120v of three-dimensional accumulation layer 100 can adopt f technology (being that the interface channel hole is of a size of f), or F technology (being that the interface channel hole is of a size of F).In the embodiment of Figure 11 A-Figure 11 B, this interface channel hole 120v adopts F technology, and substrate circuitry 0M can not need to support the figure of any f size fully like this.On the layout design of accumulation layer, address selection line 130,131 needs to adopt as the dislocation of Figure 11 B is arranged, i.e. bending dislocation on perpendicular to the direction of address selection line, with spacing be～interface channel hole 130v, the 131v of F be connected.
In order to improve yield rate, the invention allows for a kind of wide word line diode memory.As shown in figure 12, the live width Ww of its word line 120,121 be greater than bit line 130,131 live width Wb (Ww＞Wb), can adopt characteristic dimension f as bit line, and word line can be wide slightly (as＞f).This is because the yield rate of diode memory is comparatively responsive to word line defect.Particularly, in readout, a word line in unit array is selected, and a plurality of storage elements on this word line are read simultaneously then.If this word line defectiveness, then all storage elements on this root word line all can not be read.On the other hand, if defectiveness on the bit line generally can be corrected (referring to United States Patent (USP) 6,717, Figure 24 of 222) by error correction circuit (as Hamming code).In this embodiment, bit line 130-137 can be data bit line, and bit line 138 can be the error correction bit line.Can reduce ratio of defects owing to increase live width, so diode memory preferably adopts wide word line.
Use wide word line can also avoid that read current produces excessive voltage drop on word line in read procedure.Notice that the word line 120 among Figure 12 need provide electric current, i.e. electric current I for many bit lines (as 132,134,135,138)
