Abstract
According to one embodiment, a memory system includes a memory, and a processor. The memory converts an amount of charge held by a memory cell into a value. The processor executes a first process of reading first data from the memory. The processor executes a second process of reading the first data by making the memory use a first determination potential different in a case where error correction of the first data read through the first process is failed. The processor executes a third process of reading second data from the memory by making the memory use a third determination potential in a case where error correction of the first data read through the second process is succeeded. The third determination potential is the first determination potential used by the memory in a case where error correction of the first data read through the second process is succeeded.
