ABSTRACT:
A content addressable memory device including a memory to store a searchable database, a search circuit, and a first-in-first-out storage circuit. The search circuit generates a plurality of address values that correspond to unoccupied storage locations within the memory, and the plurality of address values are queued within the first-in-first-out storage circuit to enable the address values to be read in succession by an external device.
