Abstract: An integrated circuit, apparatus and method is provided for programming manufacturing information and software program information upon non-volatile storage elements on the integrated circuit. The manufacturing information includes information as to a specific processing recipe or layout used to form hardware of the integrated circuit. The software information indicates a specific revision of software used to program the integrated circuit, or a programming tool used to input the software into the integrated circuit. Combination of software and hardware is therefore embodied in non-volatile storage elements as product engineering bits. The product engineering bits can be called upon and read by the manufacturer or by the customer outside normal operation of the integrated circuit. A comparison of the hardware and software revisions will indicate possible incompatibility.

Abstract: A method is provided for programming and reading manufacturing information upon non-volatile storage elements of the integrated circuit. The manufacturing information includes the particular processing recipe and layout of the integrated circuit, each recipe or layout indicative of a specific hardware revision. The storage elements may be programmed prior to assembling the integrated circuit within a semiconductor package, and the programmed elements are read prior to shipping the packaged integrated circuit to a customer. If the read hardware revision is not qualified for release, the product will be placed in a staging area and prevented from shipping to a customer or end user. Thus, the programmed hardware revision serves to gate product at test before shipping that product to a customer. The manufacturing information is programmed by the manufacturer and is inaccessible by a customer since the address space which contains product engineering bits is known only to the manufacturer.
