MEMORY DEVICE FOR PROCESSING IN MEMORY AND OPERATING METHOD OF MEMORY DEVICE

Disclosed is a memory device which includes a plurality of memory chips. Each of the plurality of memory chips includes a plurality of memory banks and a logic circuit. In a first operation mode, the logic circuit writes first data in the plurality of memory banks based on a first command and a first address received from the host, and performs a first processing-in-memory (PIM) operation based on third data received from the host and the first data. In a second operation mode, the logic circuit writes second data in the plurality of memory banks based on the first command and the first address received from the host, and performs a second PIM operation based on fourth data different from the third data received from the host and the second data.
