Abstract

Pseudo nMOS based sense amplifier (PNSA) is proposed for high speed single-ended SRAM sensing. The voltage characteristic of pseudo nMOS is utilized to resolve the performance problem of the conventional domino sensing due to full swing bit-line requirement. Increase in dynamic power due to always-on pull-up pMOS in the pseudo nMOS structure is mitigated by introducing a feedback path. As a result, with less than 40% power overhead, the PNSA shows approximate twice better performance compared to the conventional domino sensing scheme.
