Abstract
A memory device that includes a memory array and a pre-charge selecting circuit is introduced. The memory array includes a plurality of memory cells that are coupled to a plurality of bit lines and a plurality of word lines, wherein the plurality of word lines are configured to receive an input vector. The pre-charge selecting circuit is configured to selectively pre-charge a selected bit line according to a value of the input vector. The pre-charge selecting circuit is configured to determine whether the value of the input vector is less than a predefined threshold, and generate a gated pre-charge signal to skip pre-charging the selected bit line in response to determining that the value of the input vector is less than the predefined threshold.
