    摘要: A SRAM device is provided having a plurality of memory cells. Each memory cell may include a plurality of transistors coupled in a cross-coupled inverter configuration. An NMOS transistor may be coupled to a body of the two PMOS transistors in the cross-coupled inverter configuration so as to apply a forward body bias to the PMOS transistors of the cross-coupled inverter configuration. A power control unit may control a supply voltage to each of the PMOS transistors as well as apply the switching signal to the NMOS transistor based on a STANDBY mode of the memory cell.

    摘要: A method is described that comprises modulating the power consumption of an SRAM as a function of its usage at least by reaching, with help of a transistor, a voltage on a node within an operational amplifier's feedback loop. The voltage is beyond another voltage that the operational amplifier would drive the node to be without the help of the transistor. The voltage helps the feedback loop establish a voltage drop across a cell within the SRAM.
