A semiconductor device includes a memory cell array, an address input circuit, a command input circuit, a data Input/Output (IO) circuit, a processing control circuit, a processing circuit, and a switch circuit. The processing control circuit includes a register array storing an address of an operand and determines whether an address provided from the address input circuit corresponds to the address stored in the register array. The processing circuit is configured to provide a processing result by performing an operation on data provided from the memory cell array. The switch circuit is configured to control a data path among the processing circuit, the data IO circuit, and the memory cell array and controls the data path to connect the memory cell array to the processing circuit when the address provided from the address input circuit corresponds to the address stored in the register array.

Semiconductor device capable of performing in-memory processing

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.
