Abstract
According to one embodiment, a memory system has a data transfer device which includes a first command generating unit, a second command generating unit, a first storage unit, a second storage unit, and a nonvolatile memory managing unit. The first command generator generates a first command for reading out data from a nonvolatile memory to a host apparatus. The second command generator generates a second command for internal processing of the memory system associated with a temporary memory and the nonvolatile memory. The first memory has a queue structure configured to store the first command. The second memory has a queue structure configured to store the second command. The memory manager is configured to read out the first command stored in the first memory in priority to the second command stored in the second memory and to transmit read-out command to the nonvolatile memory.
