A method is for identifying a flash memory device coupled to a host device. The flash memory device may have a page size from possible page sizes, bootstrap code stored on a first sector thereof, and a data bus for accessing data stored in the flash memory device and with a data bus size from possible data bus sizes. The method may include reading data stored in a first page of the first sector as if the flash memory device had an assumed page size and an assumed data bus size, and reading content from memory locations where error correction code (ECC) bytes of the first page are stored if the flash memory device has the assumed page size and checking whether the ECC bytes include more than a number of errors associated with the assumed page size. The method may also include if the ECC bytes do not include more than the number of errors, generating a flag signal that the flash memory device has the assumed page size and the assumed data bus size.
