Abstract

A Content Addressable Memory (CAM) circuit includes memory cells preferably formed as two memory cells each having internal nodes. A compare circuit is operative with the memory cells. A common terminal (VPL) exists for the memory cells. Capacitors are added between the internal nodes of each of the memory cells and common terminal for memory cell stability.
