Abstract

A CAMRAM capable of detecting multiple hit is disclosed. The CAMRAM includes a random address memory, a content-addressable memory, a set of index address lines and a set of multiple-hit detection address lines. The index address lines and the multiple-hit detection address lines are complementarily connected to a set of matchlines via transistors. Coupled to the index address lines and the multiple-hit detection address lines, a comparator circuit is capable of outputting a multi-hit signal when more than one of the matchlines are turned on simultaneously during an address comparison operation.
