Abstract

A memory device includes: a memory array including a plurality of memory cells and a plurality of bit lines; and a current converting circuit, coupled to the memory array. In executing a calculation operation, the memory cells of the memory array generate a source current corresponding to a calculation operation result. The source current is converted by the current converting circuit into an output value for being an input signal provided to a next calculation operation.
