ABSTRACT:
A non-volatile semiconductor memory device includes: a memory cell array, in which electrically rewritable and non-volatile memory cells are arranged; a sense amplifier circuit configured to read data of the memory cell array; and a pass/fail detection circuit configured to detect write or erase completion based on verify-read data stored in the sense amplifier circuit in data write or erase mode, wherein the pass/fail detection circuit comprises a data latch, into which a defective column isolation data is writable in accordance with a command input.
