Abstract
Based on power on of an electronic device, a location of first data in a NAND flash memory of an electronic device is determined. The first data is transmitted to a shadow RAM of the electronic device, outputting the first data is output from the shadow RAM to a host device of the electronic device through a serial peripheral interface (SPI) when accessing the location of the first data in the NAND Flash memory.
Claims15
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.
