Abstract(in English) | We have successfully demonstrated high-efficiency analog in-memory computing (AiMC) chips, which are monolithically fabricated with Si CMOS + CAAC-IGZO FETs. The AiMC chips utilize low-leakage CAAC-IGZO FETs that retain the gate voltage of Si CMOS devices to drive them in the subthreshold region and achieve an ultra-low cell current (< 1 nA/cell) and an operation efficiency of 143.9 TOPS/W. |
