A comparative performance analysis of CAMs using different model files in Spice

Reduced power without affecting delay is an important concern today. CAMs (Content Addressable Memories) are memories that implement lookup table functions using comparison circuitry. CAMs are used in table lookup Based applications such as Internet routers and processor caches. Deeply scaled technology node, with multigate devices, replacing planar MOSFETs, are expected to bring new era to CAM design. FinFET, a vertical channel gate wrap around double-gate device, has come up as the best alternative to cover up the short channel effects of planar MOSFETs. The aim of the project was to compare the N-curves of CAMs using compact models of 32-nm CMOS, 32nm-double gate FinFETs and BSIM-CMG model FinFETs in spice. The power and delay characteristics are also compared to show the superiority of BSIM-CMG CAMs.
