ABSTRACT:
A content addressable memory has a plurality of entry locations. Each entry location includes a comparison field and an action field. Comparitors are provided for each entry location, so that an input provided to the memory is compared simultaneously to the comparison fields of every entry. The action fields of all entries which match the input value are combined to generate a single output value. Each entry includes a bit which indicates whether such entry is to be deleted when a match occurs with an input value. Each entry in the memory can be assigned an arbitrary label for use in direct accessing by a central processor unit.
