A semiconductor memory device having nonvolatile memory cells arranged in matrix comprises and bit lines connected to drains of the memory cells. Latches provided for the respective bit lines or in the ratio of one latch to a number of bit lines, as are; transfer gates for electrically separating the respective latches from the bit lines. The device also having bit line voltage detection circuits for detecting voltages of the respective bit lines and latch reset circuits for inverting data stored in the respective latches in accordance with the outputs from the bit line voltage detection circuits. Therefore, data stored in each latch can be rewritten even by a very small memory cell current, resulting in stable program verify.

In the circuit operation verifying method, initialization includes inputting circuit diagram data (a net list), specification information on respective circuit elements, and input data representing waveforms with time of voltages or currents used for operation simulation, and storing the circuit diagram data to memory. Operation of a semiconductor circuit to be verified is simulated using the circuit diagram data and the input data, and momentary voltage/current values at input terminals and the like of the circuit elements are stored in the memory. During the operation simulation, whether or not the circuit elements satisfy their voltage/current specifications and time specifications are concurrently verified based on the voltage/current values stored in the memory.
