Abstract
A memory device and an operation method thereof are provided. The memory device includes: a memory array including a plurality of memory cells for storing a plurality of weights; a multiplication circuit for performing bitwise multiplication on a plurality of input data and the weights to generate a plurality of multiplication results, wherein in performing bitwise multiplication, the memory cells generate a plurality of memory cell currents; a digital accumulating circuit for performing a digital accumulating on the multiplication results; an analog accumulating circuit for performing an analog accumulating on the memory cell currents to generate a first MAC operation result; and a decision unit for deciding whether to perform the analog accumulating, the digital accumulating or a hybrid accumulating, wherein in performing the hybrid accumulating, whether the digital accumulating circuit is triggered is based on the first MAC operation result.
