Abstract: The disclosure discloses a memory device and an operation method thereof. A target memory cell and at least one replicated memory cell belonging to the same memory string are selected. A target weight value written into the target memory cell is replicated to the at least one replicated memory cell, wherein the target memory cell and the at least one replicated memory cell store the target weight value. In response to a command of reading or computing on the target memory cell received by the memory device, reading or computing is performed on the target memory cell and the at least one replicated memory cell simultaneously.
