Abstract

A charge sharing Compute In Memory (CIM) may comprise an XNOR bit cell with an internal capacitor between the XNOR output node and a system voltage. Alternatively, a charge sharing CIM may comprise an XNOR bit cell with an internal capacitor between the XNOR output node and a read bit line. Alternatively, a charge sharing CIM may comprise an XNOR bit cell with an internal cap between XNOR and read bit line with a separate write bit line and write bit line bar.
