A Cmos Electrically Configurable Gate Array

A CMOS electrically configurable gate array that combines the flexibility, efficiency, extendability, and performance of mask-programmed gate arrays with the convenience of user programmability is described. The implementation is facilitated by a novel two-terminal antifuse programmable element and a configurable interconnect technology. The chip has been fabricated using 2- mu m n-well CMOS technology with two-layer metallization. >
