Abstract
A memory system includes a non-volatile memory and a controller. The controller controls writing of data to the non-volatile memory or reading of data from the non-volatile memory, in response to a command from at least one host. The controller performs command fetching by calculating for each of a plurality of queues, a remaining processing amount, which is an amount of processing remaining for one or more commands previously fetched therefrom, selecting a queue based on the remaining processing amounts calculated for the plurality of queues, and fetching a new command from the selected queue.
