PROCESSING-IN-MEMORY (PIM) DEVICE, CONTROLLER FOR CONTROLLING THE PIM DEVICE, AND PIM SYSTEM INCLUDING THE PIM DEVICE AND THE CONTROLLER

摘要

A processing-in-memory (PIM) device includes a plurality of multiplication/accumulation (MAC) operators and a plurality of memory banks. The MAC operators are included in each of a plurality of channels. Each of the plurality of MAC operators performs a MAC arithmetic operation using weight data of a weight matrix. The memory banks are included in each of the plurality of channels and are configured to transmit the weight data of the weight matrix to the plurality of MAC operators. The weight data arrayed in one row of the weight matrix are stored into one row of each of the plurality of memory banks.
