Problems solved by technology

[0010] 3. The microcontroller can only execute the memory access program and flash memory type registered in its memory program unit. If the connected flash memory type or type is not registered in the memory program unit, it will not be able to be accessed by the microcontroller. accept or execute
[0011] 4. The data access information of the microcontroller can only be changed at the rising edge of the system clock. When the data access action is executed, the internal frequency cannot be adjusted in a timely manner, so it cannot effectively save power

Embodiment Construction

[0092] First, please refer to FIG. 2, which is a schematic structural diagram of a preferred embodiment of the flash memory storage system of the present invention; as shown in the figure, the flash memory storage system 20 of the present invention mainly includes a microcontroller 21, a temporary storage memory 25 and at least one A flash memory (device) 23, wherein the microcontroller 21 can be respectively connected to the temporary memory 25, the flash memory 23 and an application system 27, such as a host system, a playback system or a video system. The flash memory (Flash Memory) 23 includes a plurality of physical storage blocks 231 , and each physical storage block 231 has a physical address 235 .

[0093] Like the existing structure, since the data access protocols of the application system 27 and the flash memory storage system 20 are not the same, the application system 27 generally can only read or specify a logical storage block 212 that virtually exists in the mic...

Abstract

The invention relates to a flash memory storage system which comprises microcontroller, at least one flash memory of microcontroller with each flash memory including many entity storage blocks. Each entity storage block includes an entity address and many entity sectors which comprise at least one user data area and a logical address orienting fence, wherein each logical address orienting fence can write a logical address orienting data at user data area when it storage a entity data; logical address orienting data can log a corresponding logical address; a temporary storage which is connected with microcontroller can storage a connecting look-up table which can log each entity block's address and the corresponding logical address of logical storage block.

Description

technical field [0001] The invention relates to a flash memory storage system, in particular to a flash memory storage system which can not only save the startup time of the flash memory storage system, but also save the memory capacity of the temporary memory and ensure the security of data access. Background technique [0002] Existing flash memory storage system (Flash Storage), such as figure 1 As shown, the flash memory storage system 10 mainly includes a microcontroller 11, a temporary storage memory 15 and at least one flash memory (device) 13, wherein the microcontroller 11 can be respectively connected to the temporary storage memory 15, the flash memory 13 and an application system 17, while the flash memory (Flash Memory) 13 includes a plurality of physical storage blocks 131, and each physical storage block 131 has a physical address 135. [0003] Because the data access protocols of the application system 17 and the flash memory storage system 10 are not the sa...
