Sure. There are three methods to get an ID from a SPI flash chip: - RDID: The standard JEDEC Read ID command, usually 3 bytes. - REMS: Read Electronic Manufacturer Signature, 2 bytes. - RES: Read Electronic Signature, 1 byte. RDID and REMS tell you about the vendor, so it is rather easy to find out the real chip type. RES only gives you a one-byte identifier for the chip, but there is no way to find out the manufacturer.
