Abstract
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 (11b) through (14b) for storing chip data containing operation parameters of the semiconductor memory device and pass-flag storing regions (11c) through (14c) 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.
