Semiconductor memory device and method for initializing the same

摘要

A semiconductor memory device includes memory cell blocks ( 11 ) through ( 14 ) including a nonvolatile memory cell. The memory cell blocks ( 11 ) through ( 14 ) include chip-data storing regions ( 11 b) through ( 14 b) for storing chip data containing operation parameters of the semiconductor memory device and pass-flag storing regions (11c) through ( 14 c) for storing pass flags which correspond to the respective chip-data storing regions and show the validity of the stored chip data. The chip-data storing regions store the same chip data.
