Semiconductor integrated circuit and method of saving and recovering its internal state. |
摘要 |
A semiconductor integrated circuit includes; a first circuit; and a second circuit configured to control supply of a first power to the first circuit. The first circuit includes: a third circuit comprising a group of flip-flops, whose internal state is erased in response to stop of the supply of the first power; and a fourth circuit in which an internal state of the fourth circuit is saved in retention flip-flops before the supply of the first power is stopped and recovered from the retention flip-flops in response to restart of the supply of the first power. |
