1. A device comprising:
a NAND flash memory configured to store data;
a non-volatile register configured to record source addresses for data transition;
a shadow RAM connected with the NAND flash memory through a data cache from the NAND flash memory to the shadow RAM; and
a control circuit connected with the NAND flash memory and the shadow RAM, wherein the control circuit is configured to:
determine, based on power on of an electronic device, a location of first data in a NAND flash memory of the electronic device, and
transmit the first data to a shadow RAM of the electronic device.
