Trigate 6T SRAM scaling to 0.06 µm 2
2009
We present an aggressively scaled trigate device architecture with undoped channels, high-k gate dielectric, a single work function metal gate and novel BEOL processing yielding 6T SRAM bit cells as small as 0.06 µm 2 . This is the smallest SRAM cell demonstrated to date and represents the first time an SRAM based on a multi-gate FET (MUGFET) architecture has surpassed SRAM density scaling demonstrated with planar devices [1].
