1. A processing-in-memory (PIM) system comprising:
a PIM device including a storage region, a global buffer, and a multiplication/accumulation (MAC) operator, wherein the MAC operator is suitable for receiving first data and second data from the storage region and the global buffer, respectively, to perform a MAC arithmetic operation;
a PIM controller configured to control a memory mode and a MAC mode of the PIM device;
a bank input/output (BIO) line providing a first data transmission path for the first data between the storage region and the MAC operator; and
a global input/output (GIO) line providing a second data transmission path for the second data between the global buffer and the MAC operator,
wherein the PIM controller is configured to generate and transmit a memory command to the PIM device in the memory mode, and
wherein the PIM controller is configured to generate and transmit first, second, and third (first to third) MAC commands to the PIM device in the MAC mode.
