Abstract
FinFETs have emerged as alternatives to conventional bulk MOSFETs in scaled technologies due to superior gate control of the channel, lower short channel effects and higher scalability. However, width quantization in FinFETs constrains the design space of FinFET-based circuits, especially SRAMs in which transistor sizing is critical for the circuit robustness. The adverse effects of width quantization can be mitigated by appropriate device-circuit co-design of FinFETbased memories. This chapter describes some of such techniques with an emphasis on the device-circuit interactions associated with each methodology. The impact of different technology options in FinFETs like gate-underlap, fin orientation, fin height, gate workfunction and independent control of the gates on the stability, power and performance of 6 T SRAMs is discussed.
