Abstract

A semiconductor device has a first memory circuit comprising a first memory cell comprising a first field effect transistor, a second memory circuit comprising a second memory cell comprising a second field effect transistor, and a regulator for converting the first power supply potential to a second voltage value lower than the voltage value of the first power supply potential. The second gate length of the second field effect transistor is longer than the first gate length of the first field effect transistor, the first memory cell is supplied with a second power supply potential through regulator, and the second memory cell is supplied with a first power supply potential.
