Abstract
A memory system includes a host controller and a cache system. The host controller includes a host queue in which host data including a command outputted from a host are stored. The cache system includes a cache memory having a plurality of sets and a cache controller controlling an operation of the cache memory. The cache controller transmits status information on a certain set to which the host data are to be transmitted among the plurality of sets to the host controller. The host controller receives the status information from the cache controller to determine transmission or non-transmission of the host data stored in the host queue to the cache system.
