Abstract:
Analog computing-in-memory (CIM) using emerging resistive nonvolatile memory (NVM) technologies faces challenges, such as static power consumption, current flow-induced IR drop, and the need for multiple power-hungry ADCs. In this letter, we present ferroelectric capacitive array (FCA)-based energy/area-efficient CIM macro used for charge-domain multiply-and-accumulate operations, which addresses the …
