A multi-functional match cell is responsive to first and second n-bit
operands and configured so that the match cell operates as an n-bit range
match cell when the first and second n-bit operands are equivalent, as an
n-bit NOR-type CAM cell when the second n-bit operand is masked and as an
n-bit NAND-type CAM cell when the first n-bit operand is masked, where
"n" is a positive integer greater than one.
