  • MEMORY SYSTEM
    Publication number: 20200159678
    Abstract: A memory system is disclosed, which relates to technology for implementing data communication between memory devices. The memory system includes a plurality of memory devices and a memory controller. The memory devices allow a data packet composed of data and header information to be directly communicated between the memory devices. The memory controller transmits the data packet to a source memory device from among the plurality of memory devices, and receives the data packet from a last memory device from among the plurality of memory devices. Each of the memory devices hashes the header information such that the data is accessed, using a result of the hash, in address regions located at different positions.
