A software-defined network (SDN) system, device and method comprise one or more input ports, a programmable parser, a plurality of programmable lookup and decision engines (LDEs), programmable lookup memories, programmable counters, a programmable rewrite block and one or more output ports. The programmability of the parser, LDEs, lookup memories, counters and rewrite block enable a user to customize each microchip within the system to particular packet environments, data analysis needs, packet processing functions, and other functions as desired. Further, the same microchip is able to be reprogrammed for other purposes and/or optimizations dynamically.

A quaternary content-addressable memory includes multiple entries configured to match a lookup word, with each of these entries including multiple cells and with the lookup word including multiple lookup bits for matching corresponding cells of each of the entries. Each of the cells is individually configurable to be in one of multiple states identified by two bits, with these states including a first matching state for matching a value of a corresponding bit of the lookup word with the value having a first matching value, a second matching state for matching the value of the corresponding bit having a second matching value, a wildcard state for matching the value of the corresponding bit having either the first or the second matching value, and an ignore state for indicating to ignore the cell in determining whether or not the entry to which the cell belongs matches the lookup word.
