Abstract
A memory is provided that includes an analog gate voltage driver that drives the gate of a head switch transistor for a bitcell array with an analog gate voltage while the bitcell array operates in a light-sleep mode. The analog gate voltage switches the head switch transistor partially on so that the head switch transistor passes a reduced power supply voltage despite being powered by a memory power supply voltage that is greater than the reduced power supply voltage. The reduced power supply voltage has a sufficient magnitude so that the bitcell array retains its stored binary contents during the light-sleep mode.
