Abstract

This invention relates to a semiconductor device that reduces energy consumed to write data to a nonvolatile storing section. A write control circuitstores the same data as that held in MTJ elements MTJand MTJ. In a store operation storing the data held in a slave latchinto the MTJ elements MTJand MTJ, the write control circuitcompares the data stored therein with the data held in the slave latchto control whether or not to write the data to the MTJ elements MTJand MTJ. If the internally stored data coincides with the data held in the slave latch, the write control circuitperforms control not to write the data to the MTJ elements MTJand MTJ
