ABSTRACT:
A non-volatile semiconductor memory device includes a memory cell array having a plurality of electrically-programmable non-volatile memory cells; a byte scan section detecting errors of said non-volatile memory cells per byte and outputting a status of pseudo-pass even though a number of byte errors are equal to or less than a predetermined allowable number of bytes; and a bit scan section detecting bit errors of said non-volatile memory cells per bit at the time of said status of said pseudo-pass being outputted by said byte scan part, and outputting a status of pseudo-pass even though said number of said bit errors are equal to or less than a predetermined allowable number of bits.
