Project: Design and Simulation of a 6T SRAM Memory Array

The project designs and simulates a 16×16 memory array composed of six-transistor (6T) SRAM cells using HSPICE with 20 nm PTM-MG models. The circuit operates at a supply voltage of 0.9 V with two fins per transistor. The project demonstrates both read and write operations on a selected memory cell located at the intersection of the second row and third column, showing transient waveforms of the corresponding word line, bit line, and storage node. It further analyzes the impact of transistor sizing on performance by modifying the fin count of specific transistors. In one case, only the access transistors are designed with ten fins while all others retain two, and in another, the pull-down transistors use ten fins. The resulting read and write characteristics are compared to illustrate how transistor dimension scaling influences memory stability, access speed, and signal integrity.
