To provide a counting circuit which permits easy changing of conditions of detected signals and is simple and small in configuration and a nonvolatile semiconductor memory which uses the same.
The pulse counting circuit which counts the pulse number of a pulse signal and outputs the detected signal indicating that the pulse number is in existing from a first counter value to a second counter value is provided with a shift register which does not change the outputs of respective stages before the outputs are reset to an initial state by a reset signal after the outputs are once changed with the pulse signal as a trigger and count detecting logic circuits 23 and 24 which generate detected signals from the output signals of the respective stages of shift registers.
