Abstract
A ternary content addressable memory device (TCAM) may include: a cache memory storing a look-up table with respect to a calculation result of a plurality of functions; an approximation unit configured to generate mask bits; and a controller configured to obtain an approximation input value corresponding to an input key based on the mask bits and to retrieve an output value corresponding to the obtained approximation input value from the look-up table.
