ABSTRACT:
A ternary content addressable memory (TCAM) cell (100) can include two memory elements (102-0and102-1) with a single bit line (106-0and106-1) per memory element. A TCAM cell (100) can also include a compare stack (104) and two word lines (114and116) that can connect to each memory element (102-0and102-1). The memory elements (102-0and102-1) can include SRAM type memory cells with one of two data terminals connected to a pre-write potential (Vpre, which can be a ground potential, or the like). Write operations can include pre-setting the data values of memory elements (102-0and102-1) to the pre-write potential prior to providing write data via the bit lines (106-0and106-1).
