Abstract:
A memory storage system for storing information organized in sectors within a nonvolatile memory bank defined by sector storage locations spanning across one or more rows of a nonvolatile memory device, each said sector including a user data portion and an overhead portion, said sectors being organized into blocks, each sector identified by a host provided logical block address (LBA) and an actual physical block address (PBA), said host-provided LBA being received by said storage device from the host for identifying a sector of information to be accessed, said actual PBA developed by said storage device for identifying a free location within said memory bank wherein said accessed sector is to be stored, said storage system comprising:memory control circuitry; anda nonvolatile memory bank coupled to said memory control circuitry and being included in a non-volatile semiconductor memory unit, said memory bank having storage blocks each of which includes a first row-portion located in said memory unit, and a corresponding second row-portion located in said memory unit, each said memory row-portions providing storage space for two of said sectors,wherein the speed of performing write operations is increased by writing a plurality of sector information to the memory device simultaneously.
