Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Discovery is studied through inventor, the reading of FRAM and writing speed are microsecond scale, and the reading speed of EEPROM is basic and FRAM is suitable, but writing speed but reaches a millisecond grade, due to 1 millisecond=1000 microseconds, the writing speed of EEPROM is very slow comparatively speaking.And the reading of flash memory (flashmemory) is basic suitable with FRAM with writing speed, but erasing speed is slow, reach a millisecond grade, in addition, compared with EEPROM, flash storage has very high integrated level, and the flash memory that Capacity Ratio EEPROM is large can do less on the contrary.Based on these research, for realizing low cost and structure intricately need not substitute FRAM very much, inventor has made following some and has explored.
Embodiment one
Be applied to a high-speed storage device for imaging cartridge, this imaging cartridge is releasably attached on printer, as shown in Figure 1.This high-speed storage device 100 has interface portion 110, first storage area 130 and Read-write Catrol portion 120, it is characterized in that, being configured to of this first storage area 130 comprises at least two memory segments, and in Fig. 1, this first storage area is divided N number of memory segment.
For memory segment, so define: some printer often executes an original-pack storage device operated into past imaging cartridge and writes a secondary data, these operational example print one page in this way, duplicate once or execute a print out task, after different operations, the data length that printer writes toward original-pack storage device is generally different, in addition, some printer is just when changing imaging cartridge or cutting out printer power supply, just write a secondary data toward original-pack storage device, now often all information (being hereafter also referred to as a set of image-forming information) of original-pack storage device are re-write once.According to different printer characteristics, the present invention can a memory segment of configuration high-speed storage device be a byte, few tens of bytes or hundreds of bytes, then the data length of the corresponding 1 cover image-forming information of the size of a memory segment or write-once operation.
The writing speed stored due to flash is very fast, first storage area of the present embodiment is made up of flash memory, module frame chart according to Fig. 1, printer first time is when performing write operation write data toward high-speed storage device 100, if the first memory segment does not also store data, then write direct the data of write operation the first memory segment of the first storage area 130 be made up of flash memory, when second time writes data toward high-speed storage device 100, do not need to wipe the data of last time write, but the next memory segment not storing data of write, i.e. the second memory segment of the first storage area 130, when the N time (N is the predetermined integers of more than 2) is toward high-speed storage device write data, 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 flash memory has the writing speed suitable with FRAM, there is again the reading speed suitable with FRAM, need not carry out erasable to the data of flash memory by the enough large memory space of configuration, meet the read-write requirement of printer to the high-speed storage device be arranged on imaging cartridge, and decrease the size of circuit board, reduce cost, achieve good benefit.
In the present embodiment, Read-write Catrol portion can Corpus--based Method information or flag information, determines which memory segment is data are write.The method of Corpus--based Method information, such as, an Address count module is set in high-speed storage device, count from 01, often write the data of a memory segment, just the address writing data is added 1 and be updated to current counting, this counting points to the address next time write, and Read-write Catrol portion just can according to count value directly by next for the data write memory segment not writing data; Another kind utilizes in the method for flag information, a write mark region can be set in high-speed storage device, label information in this write mark region corresponds to each memory segment, such as, can write data with 1 mark, represent not yet write data with 0.So often write the data of a memory segment, just in write mark region, mark 0 corresponding for this memory segment writing data is revised as mark 1, data write is not just also write the memory segment of data by such Read-write Catrol portion when upper once write operation, the namely memory segment of mark 0 correspondence.In addition, also have other defining method, do not limited at this.
In a particular application, can also configure a power storage module on high-speed storage device, to ensure the write of data, this power storage module can be specifically electric capacity, inductance, rechargeable battery etc.
Embodiment two
On the basis of above-described embodiment one, there is in the Read-write Catrol portion of the present embodiment the first erasing control module.As shown in Figure 2, the structure of high-speed storage device is substantially identical with the above embodiments one, has interface portion 210, Read-write Catrol portion 220 and the first storage area 230.Difference is, this high-speed storage device also has Status Flag region (not shown), this Read-write Catrol portion 220 has the first erasing control module 221, described Status Flag region has write and/or erasing mark, said write mark and erasing mark are respectively used to the write of data and the situation of erasing of the memory segment marked in described first storage area, this the first erasing control module 221 is based on the information in this Status Flag region, the namely write situation of the first storage area 230, wipe in the first storage area 230 one or more be written with the data of the memory segment of data.
When being written with the data of some memory segments in the first storage area 230, because the power supply of printer supplies, first erasing control module 221 can wipe the one or more memory segment having write data in the first storage area 230, generally speaking, the data of last write are useful datas, be in the state can not writing also not erasable, and more early before data can wipe.Particularly, because flash memory is wiped by page or by block (can be called for short an erase unit below page, block), when the memory segment that one of them has been written with data takies the space of about one page, then the first erasing control module 221 directly can wipe the page at this memory segment place; If a memory segment being written with data does not reach the space of one page or a piece, then now wait for or counting, meet after reaching an erase unit, the more multiple memory segments reaching an erase unit are wiped.By that analogy, the data of new write can be written in the memory segment wiped, and for replacing previous data, such first storage area 230 can be recycled, repeatedly write and obliterated data.By such structure, can the less flash memory of configuration capacity, in the present embodiment, the erase unit that one or more memory segment is formed, can with one independently flash memory exist, also can be formed in one independently in flash memory by multiple erase unit.
Particularly, two kinds of modes are had to realize the memory segment how determining to write or to wipe.
A kind of mode stores write mark and erasing mark, see the following form 1, exemplarily indicate written information and erasure information with one-bit digital in this table, initialization write is masked as 0 expression and not yet writes data, and initialization erasing is masked as 1 and represents obliterated data.Read-write Catrol portion, according to write flag information, determines which memory segment is data are write.When the write flag information that some memory segments are corresponding represent not yet write data time, write is masked as 0, and Read-write Catrol portion can select toward this memory segment write data, and revise write and be masked as 1 after write data, amendment erasing is masked as 0; When this write flag information represent write data time, Read-write Catrol portion no longer toward this memory segment write data.
Similarly, the first erasing control module, according to the erasing flag information in described Status Flag region, determines the data of wiping which memory segment.When the erasing flag information that some memory segments are corresponding represent not yet obliterated data time, erasing is masked as 0, and the first erasing control module can the data of this memory segment of selective erasing, and after obliterated data, revise write be masked as 0, amendment erasing is masked as 1; When this erasing flag information represents that the data of this memory segment are wiped free of, Read-write Catrol portion is no longer toward the data of this memory segment of erasing.
Table 1
| Mode of operation | Write mark | Erasing mark |
| Initialization value | 0 | 1 |
| Write data | 1 | 0 |
| Obliterated data | 0 | 1 |
Another kind determines that the scheme of the memory segment that will write or wipe is, write mark or erasing mark is only stored in Status Flag region, then apparently, when writing mark expression and not writing data, also can be understood as data to wipe, when writing mark expression and having write data, also can be understood as data and be not wiped free of; For erasing mark, when wipe mark represent obliterated data time, also can be understood as data and not yet write, when wipe mark represent not yet obliterated data time, also can be understood as and write data.
Apparently, when a memory segment is not enough to a formation erase unit, an erasing mark is corresponding multiple memory segment.
Embodiment three
On the basis of above-described embodiment two, the present embodiment sets up power storage module on high-speed storage device, sees Fig. 3.Fig. 3 high speed storage device has power storage module 340, power storage module 340 connecting interface portion 310, Read-write Catrol portion 320 and the first storage area 330, this power storage module 340 puts aside electric energy when printer is powered to high-speed storage device, powers to when this Read-write Catrol portion 320 writes the first storage area 330 and/or wipes this high-speed storage device.
Carry out in read-write process at printer to high-speed storage device, power storage module 340 can put aside enough electric energy.Because memory 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 memory manufactures, when likely causing itself and printer communication, instability maybe cannot be read and write complete, therefore requires that the read or write speed uniformity of memory is high.In addition, high-speed storage device in the present embodiment also can carry out the erasing of data when write data, but if the power-on time of printer is too short, even if write operation can perform complete, and erase operation is because power-on time is not enough, and midway stopped, this is easy to damage memory.In the present embodiment, Read-write Catrol portion 320 is except utilizing the power supply of printer and reading and writing the first storage area 330 and wipe, also set up power storage module 340, even if flash manufacturing process has fine distinction to cause read or write speed different like this, or it is too short to power during the write operation of printer, Read-write Catrol portion 320 is when carrying out write and/erasing to the first storage area 330 be made up of flash memory, because power storage module 340 can be powered, even if the read or write speed of flash memory does not catch up with the read or write speed of printer a little, also can guarantee write or obliterated data time stability and integrality, thus dissimilar flash memory can be adopted, improve compatibility, improve the life-span of memory.
Particularly, in the data sectional write FLASH memory that printer is write, the data of final stage write are useful datas, for substituting data above, now more early before the data of write just become hash, the electric power storage situation of the power storage module that hash is then detected by high-speed storage device, once meet the energy demand of wiping FLASH memory, then can wipe these hashes, achieve recycling of flash memory.Certainly, the invention is not restricted to this method for deleting.
Embodiment four
Also there is power storage module and the second storage area, as shown in Figure 4 in the high-speed storage device of the present embodiment.In figure, this high-speed storage device has interface portion 410, Read-write Catrol portion 420, first storage area 431 and power storage module 440, also has the second storage area 432.This Read-write Catrol portion 420 has the second erasing control module 421, similar with embodiment two, this high-speed storage device still has Status Flag region (not shown), this Status Flag region has write and/or erasing mark, and this write mark and erasing mark are respectively used to the write of data and the situation of erasing of the memory segment marked in described first storage area or the second storage area; This second erasing control module 421 is based on the information in this Status Flag region, the namely write situation of the first storage area 431 and the second storage area 432, and the electric power storage situation of power storage module, wipe the data write in the first storage area 431 or the second storage area 432.Second erasing control module according to the method for the information in information erasing first or second storage area in Status Flag region and embodiment two similar; The structure of power storage module 440 and role and aforementioned power storage module 340 similar, do not repeat them here, only describe different places below.
According to this structure, when the first storage area 431 can not be written into the data of a memory segment again, printer is not also stored the second storage area 432 of data by Read-write Catrol portion next time toward the data write of high-speed storage device write, before the second storage area 432 can not be written into a memory segment again (generically understand be write full data before), when the electric energy that power storage module is put aside be enough to supply second wipe the data that control module 421 wipes in the first storage area 431 time, this the second erasing control module 421 wipes the data in the first storage area 431.Same method, when the second storage area 432 writes full data, the first storage area 431 continued toward obliterated data writes new data, and when the electric energy that power storage module 440 is put aside is enough to the data of erasing second storage area 432, second wipes control module 421 and wipe data in the second storage area 432.By that analogy, first storage area 431 and the second storage area 432 can be recycled write and erasing, by the multiple erase units in arbitrary storage area are wiped simultaneously, decrease the number of times that the second erasing control module performs erasing, the balanced erasable number of times of flash memory, save the power supply spending of power storage module, be conducive to the capacity reducing power storage module.
Embodiment five
On the basis of above-described embodiment three or embodiment four, the present embodiment docks oral area further and is described.Fig. 5 is the simplified structure diagram of high-speed storage device of the present invention, in figure, dotted box portion is the first charging module, COM1 comprises power line port (VCC), clock line port (CLK), input/output data line cap (I/O) and reset line port (RST), concrete being served as by electric capacity (C) of power storage module.Like this, the interface portion of high-speed storage device comprises power line port, the first charging module and other COM1s, the input connecting power line port of this charging module and other COM1s, the output of interface portion connects power storage module, and other COM1 described comprises at least one port in clock line port, input/output data line cap and reset line port.
According to this structure, charge to the electric capacity (C) as power storage module except utilizing the power line port of interface portion, also take full advantage of other COM1s of interface portion, make it possible to charge to power storage module fast, power storage module can be configured to there is larger power reservoir capacity again, and don't because obtaining too much affecting power printer from power line port, the power supply of high-speed storage device be supplied.
Embodiment six
On the basis of above-described embodiment three or embodiment four, the present embodiment docks oral area further and power storage module is described, and is the simplified block diagram of high-speed storage device, contains only interface portion and power storage module in figure shown in Fig. 6.Interface portion 610 comprises the second charging module 611, and power storage module comprises the electricity accumulating unit of more than 2 or 2, comprises the first electricity accumulating unit 641 and the second electricity accumulating unit 642 shown in figure.This second charging module 611 connects this power storage module, and this second charging module 611 gives arbitrary described electricity accumulating unit charging successively.Such as in order to make the voltage of power storage module reach voltage available rapidly, second charging module can charge first to the first electricity accumulating unit 641, after the voltage of the first electricity accumulating unit 641 reaches voltage available, charge to again the second electricity accumulating unit 642, such power storage module outwards can be powered within the very fast time, and the design of multiple electricity accumulating unit, make again electricity accumulating unit can put aside enough electric energy, extend power-on time.
According to this structure, power storage module comprises the electricity accumulating unit that multiple capacity is little or one of them capacity is less, after the printer that second charging module interface portion connects obtains electric energy, the voltage of at least one electricity accumulating unit can be made fast to reach voltage available, such high-speed storage device can respond afterwards fast in the of short duration power supply of printer, solves power storage module capacity slow problem of charging greatly.
Particularly, it is less that the first electricity accumulating unit 641 can be configured to capacity, after such quick charge, can ensure the stability writing data; And the second electricity accumulating unit 642 can be configured to capacity larger, because erase operation is few relative to write operation, the charging interval length of such second electricity accumulating unit 642 affects not at all, and the second electricity accumulating unit 642 that capacity is larger can ensure the complete execution of quite longer erase operation consuming time.But the invention is not restricted to above-mentioned capacity configuration.
