All the simulation work had been carried out using Eldo SPICE tool of Mentor Graphics.Please contact Professor Koomson for course notes and information. We have also proposed a 7T SRAM cell which has better performance metrics with existing memory cells. We, in our work, have designed and compared SRAM cells under different configurations (6T, 8T & 9T) on the basis of read and write delay, leakage power consumption and stability i.e., noise margins. This article presents the simulation of 6T, 8T and 9T SRAM cells using low power reduction techniques and develops a modified model that provides the consumer with a product that costs less and having reduced power delay product. The consumption of power and speed of SRAMs are some important issues among a number of factors that provides a solution which describes multiple designs that minimize the consumption of power and this article is also based on that. Power consumption and the speed are the major factors of concern for designing a chip along with the leakage power. Lower operating voltage will lower the stability of SRAM cell resulting in lower value of static noise margin. As the IC process technology scales, the oxide thickness and operating voltage continues to decrease. Working on low supply voltage and leakage energy has become main concern as the power consumption can be reduced significantly. Thus the demand for low size and low power memory has increased. From the last more than five decades we are scaling down the size of the CMOS devices to make the devices portable and compact in size and to get better performance in terms of access time, power dissipation, delay etc. Hence it is very important to have low power SRAMs. On chip SRAMs (Static Random Access Memory) determine the power dissipation of SoCs (System on Chips) in addition to its speed of operation. The need for low power integrated circuits is well known because of their extensive use in the electronic portable equipments.
