Abstract

The PIM system includes a PIM device and a PIM controller. The PIM device includes a first storage area, a second storage area, and a MAC operator that receives first data and second data from the first storage area and the second storage area, respectively, and performs a Multiplication-Accumulation Addition (MAC) operation. The PIM controller controls the memory mode operation and MAC mode operation of the PIM device, wherein in the memory mode, it generates a memory command signal and transmits it to the PIM device, and in the MAC mode, it transmits first to fifth MAC command signals to the PIM device.
