摘要： A technique for preventing circuit elements from being deteriorated or broken due to power-off is provided. A semiconductor memory is provided which includes a memory portion obtained by arranging electrically rewritable nonvolatile memory cells in array and a high voltage generation circuit capable of generating high voltage supplied to the memory portion. A power supply circuit and a control circuit are provided. The power supply circuit is for generating supply voltage for operating the semiconductor memory. The control circuit is for interrupting power supply from the power supply circuit to the semiconductor memory after the output voltage level of the high voltage generation circuit is lowered. After the output voltage level of the high voltage generation circuit is lowered, power supply from the power supply circuit to the semiconductor memory is interrupted. This prevents circuit elements from being deteriorated or broken due to power-off.
