Abstract
A ternary content addressable memory (TCAM) system and method of operating the same can enable a user to configure the system to operate as either a pseudo TCAM or full TCAM system. Control logic (206) can have an address modification circuit (250) coupled between multiple inputs and row decoders (206-0 and 206-1) for simultaneously writing the same mask value to mask fields of a predetermined number of memory locations in a full TCAM array.
