ABSTRACT:
An integrated circuit comprises a processor configured for fetching and executing opcodes, a system bus, and a memory coupled to the processor via the system bus. The memory includes logic circuitry for detecting functional states of the memory, wherein the memory (a) supplies one or more programmed opcodes in response to detection of first functional states of the memory, and (b) supplies a hard coded opcode in response to detection of second functional states of the memory. The second functional states of the memory can include one or more of erase, write, self-test, and check-sum. The first functional states of the memory can include a functional state other than a second functional state.
