Abstract
A memory storage system includes multiple flash memory storage devices, multiple transmission interfaces and a central control device. The central control device has a cache and respectively coupled to the flash memory storage devices through the transmission interfaces. The central control device is for maintaining a block map table (BMT) to record a mapping relationship between multiple logical blocks and the physical blocks of the flash memory storage devices and the BMT is temporarily stored in the cache. In addition, the central control device uses the communication commands to access the physical blocks of the flash memory storage devices, in which the communication commands are transmitted to multiple controllers in the flash memory storage devices through the transmission interfaces and the controllers access the physical blocks according to communication commands. In this way, the system can effectively manage multiple flash memory storage devices.
