Abstract: A host device includes a unit processor configured to generate a near data processing (NDP) request, a host expansion control circuit configured to receive the NDP request; and a local memory device configured to store data corresponding to the NDP request according to control by the expansion control circuit. In response to receiving the NDP request, the host expansion control circuit performs a request processing operation to perform a read or a write operation corresponding to the NDP request on the local memory device and performs a computation operation using the requested data corresponding to the NDP request.

Abstract: A memory expansion device includes an expansion control circuit configured to receive a near data processing (NDP) request and a remote memory device configured to store data corresponding to the NDP request according to control by the expansion control circuit. In response to the NDP request, the expansion control circuit performs a request processing operation to perform a read or a write operation on the remote memory device and performs a computation operation using the data corresponding to the NDP request.
