    摘要: In response to a read command received by a system interface unit for accessing a plurality of blocks of data stored in said non-volatile semiconductor memory, a controller carries out selective read operations of blocks of data to two memories from the non-volatile semiconductor memory. The controller also carries out parallel operations of data transferring a first block of data, which has already been subjected to error detection and error correction operations by an error correction unit, from one of the two memories to a host system via said system interface unit and of data transferring of a second block of data to be subjected to the error detection and error correction operation, from said non-volatile semiconductor memory to the other of the two memories.

    摘要: A semiconductor memory device having an electrically erasable nonvolatile memory, wherein the nonvolatile memory has management information regions for individual blocks and fault registration regions for registering fault addresses. If a block is accessed and found to be faulty, the fault registration is performed so that a partially faulty memory can be used without an increase in access time. By registering the management information address for executing the interchanges of blocks in one-to-one correspondence in the administrative information region, moreover, the blocks can be interchanged depending upon the frequency of rewriting.
