Abstract
According to one embodiment, a memory system includes a resistance change type memory including a memory cell configured to hold first data and an ECC circuit configured to detect and to correct an error in the first data; and a controller configured to control an operation of the resistance change type memory. In a read operation for the memory, when the first data from the memory cell includes an error, the memory transmits second data in which the error is corrected and a first signal to the controller. The controller transmits a control signal and a write command to the memory based on the first signal. The memory writes the second data to the memory cell based on the control signal and the write command.
