Abstract
A memory device and associated operation method are provided. The operation method is applied to the memory device to determine whether a search input and in-memory data are matched. The memory device includes a memory array and a control circuit, and the memory array includes M*N memory cells. The operation method includes the following steps. A select voltage is applied to an n-th word line. A pass-through voltage is applied to (N−1) word lines. A first search voltage is applied to an m-th first bit-line, and a second search voltage is applied to an m-th second bit-line. An m-th first sensing current and an m-th second sensing current bit are selectively generated. Then, a sensing circuit in the control circuit generates a sensing circuit output. The sensing circuit output represents whether the m-th first sensing current and the m-th second sensing current are generated.
