Abstract
An integrated circuit includes a programmable logic unit and an on-chip non-volatile memory. A JTAG port, TAP controller circuit, and program/erase control circuitry provide user access to the non-volatile memory for storage of user data. The non-volatile memory may also be used to store device data such as a serial number, product identification number, date code, or security data. Portions of the non-volatile memory may be made unavailable to the user once programmed, while other portions of the non-volatile may remain available for user access.
