Abstract: A parallel processing system includes a host and a memory device. The host includes a central processing unit configured to process processing in-memory (PIM) requests generated in a plurality of threads for in-memory processing and a memory controller configured to generate a PIM command corresponding to the PIM request. The memory device including a plurality of computing cores each including a bank and a computing circuit. The memory device is configured to perform in-memory processing in one of the plurality of computing cores according to the PIM command. The host allocates the plurality of computing cores to the plurality of threads, and PIM commands of each thread are processed using the computing core allocated to that thread.

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.
