Abstract: This
paper focuses on the DC noise margin analysis and read/write failure analysis
of the proposed 8T low power SRAM cell. In the proposed structure two voltage
sources, one connected with the Bit line and the other connected with the Bit bar
line for reducing the voltage swing during the switching activity. These two
extra voltage sources will control the voltage swing on the output node and improve
the stability. DC noise margin has been calculated by using loop gain technique
and comparison made with that of conventional 6T SRAM justify the efficiency of
the superiority of the proposed SRAM structure. Read and Write failure analyses
are also done by using Monte-Carlo simulation. Simulation has been done in 65nm
CMOS technology with 1 volt of power supply. Analog
and schematic simulations have been done in 65nm environment with the help of
Microwind3.1 by using BSimM4 model.
