  • Patent number: 12002539
    Abstract: A memory unit includes at least one memory cell and a computational cell. The at least one memory cell stores a weight. The at least one memory cell is controlled by a first word line and includes a local bit line transmitting the weight. The computational cell is connected to the at least one memory cell and receiving the weight via the local bit line. Each of an input bit line and an input bit line bar transmits a multi-bit input value. The computational cell is controlled by a second word line and an enable signal to generate a multi-bit output value on each of an output bit line and an output bit line bar according to the multi-bit input value multiplied by the weight. The computational cell is controlled by a first switching signal and a second switching signal for charge sharing.
