Original Abstract Submitted

A processing-in-memory (PIM) device includes a first memory region, a second memory region, a third memory region, and a multiplication-and-accumulation MAC circuit. The first memory region is configured to store weight data comprised of elements of a weight matrix. The second memory region is configured to store vector data comprised of elements of a vector matrix. The third memory region is configured to store constant data. The MAC circuit is configured to selectively perform a MAC arithmetic operation of the weight data and the vector data or an element-wise multiplication (EWM) arithmetic operation of the weight data and the constant data.
