Abstract(in English) | We develop 512Kb SRAM module in 45nm LSTP CMOS technology with the variation tolerant assist circuits against process and temperature. We introduce a passive resistance to the read assist circuit, and adopt the divided VDD line in the memory cell array to the write assist circuit. The SRAM cell areas with 0.245μm2 and 0.327μm2 are fabricated. From the measurements, we show that, by using our circuitry, the SNM exceeds 120mV and the write margin is improved by 15% in the worst PVT condition. |
