Memory device including a processing circuit, memory controller controlling the memory device and memory system including the memory device

Abstract

A semiconductor device may include a memory controller, which may include a request queue storing requests. Requests include a memory request including a read request to a memory device or a write request to the memory device, and a process in memory (PIM) request requesting a processing operation in the memory device. The memory controller may also include a command generator configured to generate a memory command from a memory request output from the request queue and to generate a PIM command from a PIM request output from the request queue, a command queue storing a memory command and a PIM command output from the command generator, and a command scheduler configured to control output order, output timing, or both of a memory command and a PIM command stored in the command queue.
