Description
Technical field
The present invention relates to a kind of Portable data memory device, particularly a kind of Portable data memory device of disk pattern and dynamic establishing method thereof.
Background technology
In response to such as the fast development of computing machine, digital camera, MP3 Player and mobile device electronic installations such as (mobile device) with popularize, the kenel of information category and its transmission is variation thereupon also, relatively also develops data memory device miscellaneous (Storage Media) to satisfy different demands.
The early stage data memory device summary that uses is divided into two big classes.The first kind is an electronic type solid-state storage cell arrangement, for example ROM (read-only memory) (ROM) and Random Access Storage Unit (RAM).This type of memory unit normally is embedded in computer-internal, if not can't erase, is exactly could preserve data by continued power, therefore unexpected portable purpose.Second class is the data memory device based on surface-type, and typical example is disk or CD.This type of surface-type storage device must just be able to access data by mechanical driving mechanism such as soft district or CD-ROM drive, moreover memory capacity also is subjected to its surface area and limits.If with the bigger hard disk of memory capacity, shortcoming such as being subject to again must be by motor and magnetic head running, and it is shock-sensitive, volume is big also is difficult to expect portable convenience.
Therefore, portable data memory device (Storage Media) roughly should meet following requirement: 1. non-volatile: the fundamental purpose of Portable data memory device, be be can be random the data with storing in not same electronic installation, move or duplicate, for example computing machine to computing machine, digital camera to computing machine, computing machine to purposes such as PDA(Personal Digital Assistant)s, therefore still can continue to preserve data after losing the electric power supply, be the characteristic of Portable data memory device indispensability.2. shatter-proof: the Portable data memory device must move (carrying) in the environment that can not expect, therefore becomes more important for the tolerance of bump (shock) with vibrations (vibration).Especially should reduce the possibility of mechanicalness access action,, the possibility that causes access errors or mechanical disorder be arranged because mechanicalness access action (for example hard drives) is very responsive for bump and vibrations.3. high storage density: because consider the convenience of carrying, and mobile device (for example PDA) may be more for space constraint, therefore the Portable data memory device must be apt to each branch space, and is principle with compact, so high storage density also is a very important ring.4. low power consumption: because the Portable data memory device often is applied to the data-switching between computing machine or mobile device, and mobile device is to rely on the limited various battery of density to supply with required electric power, moreover two big power consumption components such as existing processor and display screen, it is just very limited to distribute to other peripheral electric power relatively, so the low consumption of Portable data memory device electrically also is indispensable requirement.
Inspect the solid-state version Nonvolatile storage unit of existing semiconductor memory component, roughly be divided into: mask ROM (read-only memory) (MASKROM) but, once program read-only memory (OTPROM), the programmble read only memory PROM (EPROM) of can erasing, can electricity remove programmble read only memory PROM (EEPROM), flash memory (Flash Memory) wait several, wherein meet aforesaid multinomial important document fully with flash memory especially, thereby widespread usage is as the Portable data memory device.
In flash memory, can produce different memory cell arrays structures according to the difference of design, have at present NOR, NAND, DINOR and AND-type etc. several.Function distinguishing as using according to market then can classify as two kinds of CodeFlash, Data Flash.Wherein, Code Flash is a framework with NOR-type Flash mainly, generally is applied in the storage unit capacity and is not on the very big product, such as the BIOS of PC, mobile phone, PDA etc.Data Flash is a framework with NAND-type Flash usually then, its capacity is usually all greater than more than the 16MB, the storage that is suitable as mass data with read, generally be applied in such as digital camera, MP3 Player, computing machine and various mobile device etc., based on as data memory device (Storage Media).
