Abstract
A circuit sleep method includes: writing all data stored in a memory unit into a current data-backup block and performing a check calculation on the data written into the current data-backup block to obtain a first verification value; powering down the circuit to make the circuit enter a sleep mode; restarting the circuit and determining whether the processing unit has written all the data stored in the memory unit into the current data-backup block before the circuit enters the sleep mode; performing the check calculation on the data stored in the current data-backup block to obtain a second verification value and comparing the first verification value with the second verification value; and writing back the data stored in the current data-backup block to the memory unit in a case that the first verification value and the second verification value are the same.
