ABSTRACT:
A semiconductor integrated circuit device includes connected TC unit type ferroelectric memory which includes series connected memory cells each having a cell transistor having a source terminal and a drain terminal and a ferroelectric capacitor inbetween the two terminals, a first power supply circuit which generates a first power supply potential supplied to the gate of the cell transistor when the cell transistor is in a standby state, and a second power supply circuit. The second power supply circuit generates a second power supply potential supplied to the source or drain of the cell transistor and starts operating following the start-up of the first power supply circuit after a power-on.
