MEMORY SYSTEM

摘要

According to one embodiment, a memory system includes a first memory, a second memory, a third memory, a data transmission controller, and a processing unit. The second memory is configured to store first management information to manage the first memory. The third memory is configured to be accessed at a speed higher than the second memory. The processing unit causes the data transmission controller to transmit second management information and third management information from the second memory to the third memory in a burst mode before a read process is performed on the first memory. The second management information and the third management information are related to the read process and are included in the first management information. The processing unit performs the read process on the first memory using the second management information and the third management information stored in the third memory.
