FLASH MEMORY BASED STORAGE SYSTEM AND OPERATING METHOD

摘要

A flash memory based storage system and operating method are provided. A host of the storage system requests an erase unit size from the storage device and uses a multiple of the erase unit size to partition a logical address. Each host block may be assigned a state selected from a group of states including: an open state in which an erase unit of the storage device is allocated, a write state in which data is written at an erase unit of the storage device, a close state in which a write operation is no longer performed, and an invalidate state in which valid data of a host block is invalidated.
