Emerging Memory/Logic Design
Scaling of conventional CMOS technology has been motivated by the need for higher integration density and performance over the last few decades. Static power consumption is a major concern when designing nano-scaled integrated circuits, due to the exponential dependence of subthreshold current on the threshold voltage. Embedded SRAM comprises a dominant portion of chip area, and the power consumption in modern SoCs. In SRAM cells, where the contents must be retained for long durations with a constant power supply, the subthreshold current is a significant source of power consumption. Therefore, when designing future SRAM cells for low-power applications, a vital design objective is to minimize the subthreshold current. Our goal is to use emerging technologies such as FinFET and non-volatile memories to design an ultra-energy efficient memories with high speed and density. In the following our work have been categorized to cache design in circuit and architecture and application/user levels.
