DIFFERENTIAL CHARGE SHARING FOR COMPUTE-IN-MEMORY (CIM) CELL

Abstract:

Certain aspects of the present disclosure provide a circuit for in-memory computation. The circuit generally includes a memory cell having a bit-line and a complementary bit-line, a first capacitive element coupled to the bit-line, a second capacitive element coupled to the complementary bit-line, a processing circuit, a first switch coupled between a first input of the processing circuit and the bit-line, and a second switch coupled between a second input of the processing circuit and the complementary bit-line
