Abstract
A programmable logic device having content addressable memory is disclosed. In a preferred embodiment, the programmable logic device includes reconfigurable dual mode memory suitable for operating as a content addressable memory in a first mode and a random access memory in a second mode is disclosed. Mode control switch circuitry may be provided to selectively enable a user to configure the dual mode memory as either content addressable memory or random access memory.
