專利摘要(中)
A multi-bit computing circuit for computing-in-memory applications is controlled by an input port and includes a memory cell array and a capacitor sharing unit. The memory cell array includes a plurality of memory cells connected to the input port. The memory cells store a weight which is formed in two’s complement. The capacitor sharing unit includes a plurality of switches, a plurality of capacitors and a sense amplifier. The switches are electrically connected to the memory cells, respectively. The capacitors are electrically connected to the switches, respectively. The sense amplifier is electrically connected to the capacitors and generates a total operational value. The capacitors are located among the switches and the sense amplifier, and the switches are switched to enable the total operational value to be equal to the input value multiplied by the weight. The present disclosure utilizes 8T SRAM cells without an extra DAC structure.
