MOS implementation of winner-take-all network with application to content-addressable memory

Implementation of a winner-take-all (WTA) network suitable for implementing a nearest-match content-addressable memory (CAM) is presented. The resolution of the network in differentiating between words with large bit mismatches is presented. A measure of the time performance of the network is also given. A fully functional 16 word by 12 bit chip has been fabricated through MOSIS using 2 mu m double-metal CMOS technology. >
