Embodiment Construction
[0041] The present invention mainly adds a high-speed cache in the flash memory system, so that the written data is processed in the high-speed cache before being stored in the flash memory, so as to reduce the program of writing and erasing (Erase) times on the flash memory. And by means of the time-sharing processing of the data bus bandwidth, the cache is sufficient to provide access according to proper allocation. Furthermore, through the design of different cache blocks in the cache, the present invention can control different cache blocks to achieve synchronous execution of data temporary storage and data writing into flash memory. In this way, the access performance of the flash memory system and the service life of the memory can be effectively improved at the same time.
[0042] figure 1 and figure 2 , is a block diagram of an embodiment of the flash memory system of the present invention and a schematic diagram of the architecture of the cache. Such as figure 1 ...
