A NAND or NOR content-addressable memory (CAM) cell, which selectively use single port, tow ports, or three ports for operations depending on design requirements. Only n-channel transistors or p-channel transistors design these NAND or NOR CAM cells. In such designs, one-port bit line with one-port word line, or one-port bit line with two-port word lines, or two-port bit lines with two-port word lines are provided for meeting different operations and pruposes.
