摘要

A memory unit is controlled by a first word line and a second word line. The memory unit includes a memory cell and a multi-bit input local computing cell. The memory cell stores a weight. The memory cell is controlled by the first word line and includes a local bit line transmitting the weight. The multi-bit input local computing cell is connected to the memory cell and receives the weight via the local bit line. The multi-bit input local computing cell includes a plurality of input lines and a plurality of output lines. Each of the input lines transmits a multi-bit input value, and the multi-bit input local computing cell is controlled by the second word line to generate a multi-bit output value on each of the output lines according to the multi-bit input value multiplied by the weight.
