Abstract: A method and apparatus are disclosed for writing to a large content addressable memory (CAM) array without causing substantial power supply current surges, for providing fully static CMOS memory cells, for providing a consistent precharge of bit and bit bar lines, for providing a column write capability, and for increasing a read current while reducing a read disturbance probability. Each memory cell in the CAM array has (a) a data write circuit for accepting data, (b) a latch circuit for latching the data in the memory cell, (c) a hold circuit to allow holding the data or writing new data, (d) a data compare circuit for comparing the new data to the stored data, and (e) a data read circuit for reading the stored data.
