Abstract: A method includes simulating a first design of a semiconductor memory that includes at least one device disposed between and coupled to a memory bit cell and to a power supply line, determining if at least one simulated operational value of the semiconductor memory is above a threshold value, and adjusting at least one of a size of the device or a type of the device if the at least one simulated operational value is below the threshold value. The memory bit cell is disposed in a column including a plurality of bit cells. The size or type of the device is repeatedly adjusted and the design of the semiconductor memory is repeatedly simulated until the at least one simulated operational value is at or above the threshold value.

Abstract: The present invention describes circuitry and a method of providing a low power WRITE mode of operation for an integrated circuit comprising an SRAM memory to provide a reduced IDDQ relative to the IDDQ of a full active mode. In one aspect, the circuitry includes an SRAM memory array, mode control circuitry coupled to the array and configured to alter a supply voltage level to the SRAM array based on a mode of operation. The circuitry also includes control inputs coupled to the mode control circuitry for selecting one of the low power write mode, the full active mode, and optionally a retention mode of operation. The mode control circuitry is configured to receive the control inputs to select one of the three modes of operation, and to alter one or more supply voltage levels to the array, for example, the Vss supply voltage using a Vss supply circuit and the Vdd supply voltage using a Vdd supply circuit, based on the selected mode of operation.
