ABSTRACT:
A semiconductor integrated circuit device according to the present invention includes a booster circuit 1 for raising an external power supply voltage Vccext, a level detecting circuit 2 for detecting fluctuation in a stepped-up voltage Vccint2, an internal voltage generating circuit 3 for generating an internal voltage Vccint on the basis of the stepped-up voltage Vccint2, an address buffer 4, an address decoder 5, and a memory cell array 6 of an EEPROM structure. The level detecting circuit 2 includes a first level detecting part for performing level detection during a memory access state, and a second level detecting part for performing level detection during a stand-by state. During the stand-by state, the internal voltage generating circuit 3 short-circuits the stepped-up voltage Vccint2 and the internal voltage Vccint. The second level detecting part has lower power consumption than that of the first level detecting part, so that it is possible to reducing the power consumption during the stand-by state without lowering the driving voltage.
