Abstract: According to one embodiment, a memory circuit includes a plurality of nonvolatile memory cells and a control circuit. Each of the plurality of nonvolatile memory cells loses stored data when the stored data is read. The control circuit reads data from a first memory cell among the plurality of memory cells as designated by a first instruction but does not write the data read from the first memory cell back to the first memory cell after the first instruction is received. The control circuit reads data from a second memory cell among the plurality of memory cells as designated by a second instruction and writes the data read from the second memory cell back to the second memory cell after the second instruction is received.
