ABSTRACT:
A memory device (100) includes a user device information sector (122) in addition to normal sectors (124) of a memory array. The user device information sector includes a product identification field (240) and a restricted address list field (250), and optionally includes a customer identification number field (220) and a serial number field (230). The product identification field includes such information as the manufacturer ID, a part number ID, package/speed identification, temperature/voltage identification, and byte locations for special options. The device identification field is factory programmed using a high voltage enabling signal applied to a write control logic circuit (102) in the memory device in conjunction with a "Device Information Sector Program" instruction is applied to the SPI command and control logic (110). The device information sector is read from the application using a "Read Device Information" instruction. Inadvertent corruption of the device information sector is avoided since a high voltage typically is not available in the application, and the "Device Information Sector Program" instruction is not in the application command set.
