Abstract

See full text

Stable SRAM cells utilizing Independent Gate FinFET architectures provide improvements over conventional SRAM cells in device parameters such as Read Static Noise Margin (RSNM) and Write Noise Margin (WNM). Exemplary SRAM cells comprise a pair of storage nodes, a pair of bit lines, a pair of pull-up devices, a pair of pull-down devices and a pair of pass-gate devices. A first control signal and a second control signal are configured to adjust drive strengths of the pass-gate devices, and a third control signal is configured to adjust drive strengths of the pull-up devices, wherein the first control signal is routed orthogonal to a bit line direction, and the second and third control signals are routed in a direction same as the bit line direction. RSNM and WNM are improved by adjusting drive strengths of the pull-up and pass-gate devices during read and write operations.
