Study discovery through the inventor, read and the writing speed of FRAM is the microsecond grade, and the reading speed of EEPROM is basic suitable with FRAM, but writing speed has but arrived the millisecond grade, because 1 millisecond=1000 microseconds, the writing speed of EEPROM is to be very slow comparatively speaking.And reading with writing speed of flash memory (flash memory) is basic suitable with FRAM, but erasing speed is slow, reached the millisecond grade, in addition, compare with EEPROM, the Flash storer has very high integrated level, and the flash storer that volume ratio EEPROM is large can be done littlely on the contrary.Based on these research, for realizing the too alternative FRAM of intricately of low cost and structure, the inventor has made some following explorations.
Embodiment one
A kind of high-speed storage device that is applied to imaging cartridge, this imaging cartridge is releasably attached on the printer, as shown in Figure 1.This high-speed storage device 100 has interface portion 110, the first storage area 130 and read-write control part 120, it is characterized in that, being configured to of this first storage area 120 comprises at least two memory segments, and this first storage area is divided N memory segment among Fig. 1.
For memory segment, so define: some printer whenever executes an operation and advances toward the original-pack memory storage of imaging cartridge to write a secondary data, these operational example are printed one page in this way, duplicate once or execute one time print out task, after the different operations, printer is generally different toward the data length that original-pack memory storage writes, in addition, some printer is just when changing imaging cartridge or cutting out printer power supply, just write a secondary data toward original-pack memory storage, often again write all information (hereinafter also being referred to as a cover image-forming information) of original-pack memory storage once this moment.According to different printer characteristics, the utility model can the configuration high-speed memory storage a memory segment be a byte, dozens of byte or hundreds of bytes, the data length of the corresponding 1 cover image-forming information of the size of a memory segment or write-once operation then.
Because the writing speed of flash storage is very fast, the first storage area of present embodiment is made of the flash storer, according to module frame chart shown in Figure 1, when printer is carried out the write operation data writing toward high-speed storage device 100 for the first time, if the first memory segment is not also stored data, the first memory segment of the first storage area 130 of being made of the flash storer then writes direct the data of write operation, for the second time toward high-speed storage device 100 data writing the time, do not need the data that the last time writes are wiped, do not store the data storage segmentation but write the next one, i.e. the second memory segment of the first storage area 130, when the N time (N is the predetermined integers more than 2) past high-speed storage device data writing, data are write the N memory segment of the first storage area 130, by that analogy, until the first storage area 130 can not be written into the data (generically understanding is when writing full data) of a memory segment again.Because the flash storer has the writing speed suitable with FRAM, have again the reading speed suitable with FRAM, need not carry out erasable to the data of flash storer by disposing enough large storage space, satisfy printer to being installed in the read-write requirement of the high-speed storage device on the imaging cartridge, and reduced the size of circuit board, reduce cost, obtained preferably benefit.
In the present embodiment, the read-write control part can based on statistical information or flag information, determine which memory segment is data write.Method based on statistical information, for example, an address counting module is set in high-speed storage device, since 01 counting, whenever write the data of a memory segment, the address that just will write data adds 1 and is updated to current counting, and this counting points to the address that next time writes, and the read-write control part just can directly write data the memory segment that the next one does not have data writing according to count value; Another kind utilizes in the method for flag information, can in high-speed storage device, arrange one and write mark region, this label information that writes in the mark region corresponds to each memory segment, for example can with 1 mark data writing, represent not yet data writing with 0.So whenever, write the data of a memory segment, sign 0 corresponding to this memory segment that just will write data in writing mark region is revised as sign 1, the read-write control part just writes data the memory segment that does not also have data writing when next time write operation like this, namely indicates the memory segment of 0 correspondence.In addition, else determine method in addition, do not limited at this.
In concrete the application, can also be in power storage module of high-speed storage device configuration, to guarantee writing of data, this power storage module specifically can be electric capacity, inductance, rechargeable battery etc.
Embodiment two
On the basis of above-described embodiment one, have first in the read-write control part of present embodiment and wipe control module.As shown in Figure 2, the structure of high-speed storage device and the above embodiments one are basic identical, have interface portion 210, read-write control part 220 and the first storage area 230.Difference is, this high-speed storage device also has Status Flag zone (not shown), this read-write control part 220 has first and wipes control module 221, described Status Flag zone has and writes and/or wipe sign, said write sign and wipe the situation that writes and wipe of data that sign is respectively applied to the memory segment in described the first storage area of mark, this first wipes control module 221 based on the information in this Status Flag zone, the situation that writes of the first storage area 230 is namely wiped in the first storage area 230 one or more and has been write the data of data storage segmentation.
The data of some memory segments in the first storage area 230, have been write, because the power supply of printer is supplied with, first wipes control module 221 can wipe in the first storage area 230 the one or more memory segment of data writing, generally speaking, the data that write for the last time are useful datas, and data before can be wiped.Particularly, because the flash storer is wiped by page or leaf or by piece (page or leaf, can be called for short below the piece erase unit), when one of them has write the data storage segmentation and takies the space of about one page, then first wipe control module 221 and can directly wipe the page or leaf at this memory segment place; If one has write the space that the data storage segmentation does not reach one page or, then wait for this moment or counting, satisfy reach an erase unit after, a plurality of memory segments that will reach again an erase unit wipe.By that analogy, the data that newly write can be written in the memory segment of having wiped, and are used for replacing previous data, and such the first storage area 230 can be recycled, and repeatedly writes and obliterated data.By such structure, can the less flash storer of configuration capacity, in the present embodiment, the erase unit that one or more memory segments consist of, can with one independently the flash storer exist, also can a plurality of erase units be formed on one independently in the flash storer.
Particularly, there is dual mode to realize the memory segment that how to confirm will write or wipe.
A kind of mode is to write sign and wipe sign in the Status Flag area stores, see the following form 1, exemplarily indicate writing information and erasure information with one-bit digital in this table, initialization writes and is masked as 0 and represents not yet data writing, and initialization is wiped and is masked as 1 and represents obliterated data.The read-write control part determines according to writing flag information which memory segment is data write.When some memory segments corresponding write flag information and represent not yet data writing the time, write and be masked as 0, the read-write control part can be selected toward this memory segment data writing, revises to write being masked as 1 behind data writing, revises to wipe being masked as 0; When this write flag information and represents data writing, the read-write control part was no longer toward this memory segment data writing.
Similarly, first wipe control module according to the flag information of wiping in the described Status Flag zone, the data of determining to wipe which memory segment.When some memory segments corresponding wipe flag information and represent not yet obliterated data the time, wipe and be masked as 0, the first and wipe the data that control module can this memory segment of selective erasing, after obliterated data, revise to write being masked as 0, revise to wipe being masked as 1; Wipe flag information when this and represent that the data of this memory segment are wiped free of, the read-write control part is no longer toward the data of wiping this memory segment.
Table 1
| Mode of operation | Write sign | Wipe sign |
| Initialization value | 0 | 1 |
| Data writing | 1 | 0 |
| Obliterated data | 0 | 1 |
The scheme of another kind of definite memory segment that will write or wipe is, only storage writes sign or wipes sign in the Status Flag zone, then apparently, when writing sign and represent not data writing, also can be understood as data wipes, when writing sign and represent data writing, also can be understood as data and be not wiped free of; For wiping sign, when wiping sign and represent obliterated data, also can be understood as data and not yet write, when wiping sign and represent not yet obliterated data, also can be understood as data writing.
Apparently, when a memory segment is not enough to consist of an erase unit, wipes sign for one and be corresponding a plurality of memory segments.
Embodiment three
On the basis of above-described embodiment two, present embodiment is set up power storage module at high-speed storage device, sees Fig. 3.Fig. 3 high speed memory storage has power storage module 340, power storage module 340 connecting interface sections 310, read-write control part 320 and the first storage area 330, this power storage module 340 is put aside electric energy when printer is powered to high-speed storage device, give this high-speed storage device power supply when 320 pairs of the first storage areas 330 of this read-write control part write and/or wipe.
At printer high-speed storage device is carried out in the read-write process, power storage module 340 can be put aside enough electric energy.Because storer read or write speed under different electric power thus supplied has fine distinction, and printer is consistent often to the power-on time of imaging cartridge high-speed memory, nuance when storer is made, unstablely in the time of might causing itself and printer communication maybe can't read and write completely, therefore require the read or write speed consistance of storer high.In addition, high-speed storage device in the present embodiment also can carry out wiping of data in data writing, if but the power-on time of printer is too short, and write operation can complete, and erase operation is because of power-on time deficiency Halfway Stopping, and this is easy to damage storer.In the present embodiment, read-write control part 320 is except the power supply that utilizes printer is read and write and wiped the first storage area 330, also set up power storage module 340, even the flash manufacturing process has fine distinction to cause read or write speed different like this, perhaps the write operation of printer time power supply is too short, the read-write control part 320 the first storage area 330 that is made of the flash storer is write and/when wiping, because power storage module 340 can be powered, even the read or write speed of flash storer does not catch up with the read or write speed of printer a little, also can guarantee to write or stability and integrality during obliterated data, thereby can be suitable for dissimilar flash storeies, improve compatibility, improved the life-span of storer.
Particularly, the data sectional that printer is write writes in the FLASH storer, the data that final stage writes are useful datas, be used for substituting the data of front, the data that write more early this moment have just become gibberish, and the electric power storage situation of the power storage module that gibberish is then detected by high-speed storage device is in case satisfy the energy demand of wiping the FLASH storer, then can wipe these gibberishes, realize the recycling of flash storer.Certainly, the utility model is not limited to this method for deleting.
