1. A processing-in-memory (PIM) device comprising:
a data storage region configured to store vector data and weight data, and configured to output the vector data based on a first single external command;
a global buffer configured to store the vector data read from the data storage region based on the first single external command; and
an arithmetic circuit configured to receive the vector data from the global buffer, to receive the weight data from the data storage region, and to generate a calculation result by performing a calculation on the vector data from the global buffer and the weight data from the data storage region.
