چکیده

Noise margin at read, at write and in stand-by is analyzed for the 6 transistor SRAM cell in a 0.18 μm process considering specific low power conditions such as low supply voltage and source-body biasing. These conditions reduce the noise margin. By using an asymmetrical cell design in which read is performed only on one of the two complementary bit lines, the noise margin can be improved and the bias limits extended for a reduced power consumption.

Analysis of Leakage Current and SNM For 7T SRAM Cell in Nanometre Era

: In the microprocessors world SRAM play a vital role, but as the technology is scaling in nanometer, leakage current and leakage power both are the most known problems for SRAM cells in low power applications. More than 40% of the total power of the SRAM is waste due to the leakage through transistor. This paper compares the working, performance and results of two different SRAM topologies; a ...

Dynamic Noise Margin Analysis of a Low Voltage Swing 8T SRAM Cell for Write Operation

This paper presents the analysis of dynamic noise margin of proposed 8T static random access memory (SRAM) cell. The proposed SRAM cell has two voltage sources, one connected to the bit line and the other is connected to bitbar line. These voltage sources are used to reduce the swing voltage at the output nodes. This reduction of swing voltage causes the reduction in dynamic power dissipation o...

Super-Fast Low Power (SFLP) SRAM Cell for Read/Write Operation

In this paper a Super-Fast Low-Power (SFLP) static random access memory (SRAM) cell has been proposed. The SFLP cell contains two tail transistors in the pull-down path of the respective inverter to minimize the write power consumption The cell is simulated in terms of speed, power and read stability. The simulated results show that the read and write power of the proposed cell is reduced up to...
