摘要：
A device employs a method for determining the data bus width of a non-volatile memory, such as NAND flash memory. The method performs at least two read operations on the non-volatile memory so as to test the changing of selected data bits. The method may be performed such that weak pull down and pull up operations are performed to test the data outputs of the non-volatile memory.
