  • Publication number: 20240069747
    Abstract: A memory controller of a memory system classifies input and output commands issued by a host into a group of read commands and a group of write commands, and manages the group of read commands and the group of write commands using first and second queues, respectively. The controller continuously processes a first group of commands among the group of read commands and the group of write commands until a first time period has elapsed from a start of the continuous processing of the first group of commands. In response to the first time period having elapsed, the controller switches a process target from the first group of commands to a second group of commands that is different from the first group of commands and selected among the group of read commands and the group of write commands.
