An eight-transistor (8T) cell is proposed to improve variability tolerance and low-voltage operation in high-speed SRAM caches. While the cell itself can be designed for exceptional stability and write margins, array-level implications must also be considered to achieve a viable memory solution. These constraints can be addressed by modifying traditional 6T-SRAM techniques and conceding some design complexity and area penalties. Altogether, 8T-SRAM can be designed without significant area penalty over 6T-SRAM while providing substantially improved variability tolerance and low-voltage operation with no need for secondary or dynamic power supplies. The proposed 8T solution is demonstrated in a high-performance 32 kb subarray designed in 65 nm PD-SOI CMOS that operates at 5.3 GHz at 1.2 V and 295 MHz at 0.41 V. © 2008 IEEE.
