專利摘要(英)
A memory unit with multiple word lines for a plurality of non-volatile computing-in-memory applications is configured to compute a plurality of input signals and a plurality of weights. The memory unit includes a non-volatile memory cell array, a replica non-volatile memory cell array and a multi-row current calibration circuit. The non-volatile memory cell array is configured to generate a bit-line current. The replica non-volatile memory cell array includes a plurality of replica non-volatile memory cells and is configured to generate a calibration current. Each of the replica non-volatile memory cells is in the high resistance state. The multi-row current calibration circuit is electrically connected to the non-volatile memory cell array and the replica non-volatile memory cell array. The multi-row current calibration circuit is configured to subtract the calibration current from a dataline current to generate a calibrated dataline current. The dataline current is equal to the bit-line current.
