Abstract

The disclosure described a substrate bias generating circuit in which an internal RAS (Row Address Strobe) signal and an internal CAS (Column Address Strobe) signal, both of which are synchronized with an external RAS signal and external CAS supplied from outside in addition to self-oscillator, activate circuits comprising capacitors and rectifying elements respectively so as to reduce wattage dissipation thereof during holding time of RAM and be obtained increased charge pump current during operation thereof.
