    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 power management device and static random access memory (SRAM) architecture with dynamic supply voltages reduce active power leakage in SRAM cells. When a cell is inactive, a low level supply voltage is applied to the source line connected to the cell to maintain the data stored in the cell. However, before a cell is accessed (e.g., during a read or write operation), the source line is raised to a high level supply voltage.
