Abstract
A memory system includes a plurality of memory chips, a memory, and a controller. The memory chips are capable of operating in parallel. The memory includes a physical channel region and a plurality of virtual channel regions, each corresponding to one of a plurality of processes executed on the memory chips according to the requests. The controller stores the requests issued from the host in the physical channel region in order of acquisition from the host, and an entry for each of the requests in one of the virtual channel regions. When a required degree of parallelism of the processes is less than a threshold, the controller selects a next request to be executed using the physical channel region. When the required degree of parallelism is greater than or equal to the threshold, the controller selects a next request to be executed using one of the virtual channel regions.
