DUAL RAIL POWER SUPPLY SCHEME FOR MEMORIES

摘要

A dual rail memory operable at a first voltage and a second voltage includes an input circuit, an output circuit and a clock generator circuit coupled with the input circuit. The input circuit is operable to receive at least a first input signal referenced to the first voltage and to generate a second input signal referenced to the second voltage. The output circuit is operable to receive at least a first output signal referenced to the second voltage and to generate a second output signal referenced to the first voltage. The clock generator circuit is operable to receive a first clock signal referenced to the first voltage and to generate a second clock signal referenced to the second voltage, a logic state of the second clock signal being a function of a logic state of the first clock signal.
