Fault-tolerant content addressable memory

Abstract

We analyze the error behavior of content addressable memories and provide necessary and sufficient conditions to protect them. Single error tolerant designs are demonstrated for bit- and byte-organized content addressable memories. This level of protection is equivalent to that of the conventional ECC protection in memory subsystems.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
