Design and Performance Analysis of SRAM Cells

The requirement for maximum noise-tolerant SRAM cells with low dissipating power is increasing day-by-day. The paper presents 9T SRAM cell which targets certain stability parameters, capable of tolerating the maximum noise with low dissipating power. 9T SRAM is an isolated SRAM with two separate read ports that help in enhancing the stability parameters. This is done at 1 V using a 45 nm technology node. For simulation and analysis of stability parameters, Cadence Virtuoso and EDA tanner tools are used. The work is also compared with previous works of various 6T, 7T and 8T SRAM cells.
