Abstract:
1. An electronic device, comprising: a NAND flash memory; an auxiliary memory, for storing a first code for detecting a correct read command sequence associated with the NAND flash memory, and for storing a second code from the auxiliary memory for detecting a data bus width of the NAND flash memory, wherein said first code comprises a plurality of candidate read command sequences; and a controller, respectively connected to the NAND flash memory and the auxiliary memory, for reading said first code and said second code from the auxiliary memory, executing the first code during a boot procedure of the electronic device to detect the correct read command sequence among said plurality of candidate read command sequences for accessing the NAND flash memory, and executing the second code to obtain the data bus width; wherein the second code corresponds to a third detection procedure comprising steps of:
