ABSTRACT:
There is provided non-volatile semiconductor memory a capable of performing an accurate program verify, by suppressing the power supply noise generated at the time of a program verify. An output buffer includes a mode discriminating circuit for discriminating an ordinary reading mode and a programming mode, and a load circuit. Connection/disconnection of the load circuit is determined by a NOR gate receiving a verify activation signal which is activated at the time of verify, in such a manner that the load circuit is put in a disconnected condition at the time of the ordinary reading, and in a connected condition at the time of the program verify.
