Abstract
According to one embodiment, a memory system includes a semiconductor memory including a memory cell, and a controller configured to control the semiconductor memory and capable of creating second data based on first data read from the memory cell. Upon receiving a physical erase request for the first data held in the memory cell from an external device, the controller transmits one of an erase instruction and a write instruction for the second data to the semiconductor memory.
