  • Patent number: 6591329
    Abstract: A flash memory system including a memory manager. The memory manager manages data transmission and reception between a host computer and a flash memory. The memory manager mutually converts a logical address in which the flash memory is accessible from the host computer, and a physical address has an actual address of the flash memory. It stores a change of internal information as &Dgr; record in said flash memory and after resetting, restores an internal state to a state before the resetting by information of the &Dgr; record. The flash memory system can be realized in which the delay of the writing/reading time can be decreased, or writing operation can be relatively easily performed, high speed operation is possible and defective sectors, defective bits and the like can be adequately managed.

  • Patent number: 6581132
    Abstract: A flash memory system of the present invention comprises a memory manager for managing data transmission/reception between a host computer and a flash memory, said memory manager having an address conversion table for converting a logical address given to the flash memory from the host computer and a physical address as an actual address of the flash memory, said address conversion table being defined in accordance with minimum erasing units of the flash memory. This can realize a flash memory system which has little delay in a writing/reading time, enables a high-speed operation, and can adequately manage defective sectors, defective bits, and the like.
