According to one embodiment, a memory system includes a NAND-type flash memory and a memory controller. The memory controller includes a monitoring module and a determination module. The monitoring module acquires an elapsed time from the start of data erase of a first block in the NAND-type flash memory. The determination module determines whether the elapsed time has exceeded a reference time before completion of the data write in the first block.
