Memory-Logic Hybrid Gate with 3D-Stackable Complementary Latches for FinFET-based Neural Networks

A memory-logic hybrid gate with complementary resistive switching pairs on vias in BEOL FinFET technologies with an area-efficient, 3D-stackable structures is proposed. Stable output logic stages enabled by the complementary states on the RRAM pair have been demonstrated. Through stacked-vias architectures, logic operations based on multiple non-volatile states are achieved.
