Abstract

According to one embodiment, in a memory system, a controller is configured to write a first data among write data to be written across the multiple chips of the first memory area into part of the first memory area and write, in response to a power supply disconnection being detected before writing a second data among the write data into the first memory area, a first information about a storage location where the second data has been stored and the second data into the second memory area. The controller is configured to read, in response to power return being detected, the first data from the part of the first memory area, and read the first information from the second memory area. The controller is configured to generate a second information about a reference location to access the second data based on the read first information.
