ABSTRACT:
The present invention relates to electronic circuits that retain identical functionality and performance under RAM and hard-wire ROM fabrication options. An integrated circuit (IC) providing identical functionality and performance in two selectable fabrication options, wherein: a first selectable option comprises a user configurable circuit; and a second selectable option comprises a hard-wired circuit in lieu of said user configurable circuit. Such a programmable to hard-wire conversion provides a significant IC cost reduction at minimal NRE cost and improved reliability.
