Abstract
Provided is a memory system including a host system including a memory controller configured to control a read or write operation for a plurality of memory ranks, based on target or non-target information for the plurality of memory ranks, and a memory device including a storage configured to store on-die termination (ODT) information of the memory ranks. Here, the memory controller is further configured to determine a target rank to be read or written, and transmit information about the determined target rank, to the memory device, and the memory device is further configured to perform a comparison of the ODT information of the memory ranks stored in the storage with target or non-target information received from the memory controller, and change an ODT value of the target rank, based on target information received from the memory controller based on a result of the comparison.
