專利摘要

A segmented search line circuit device for content addressable memory is provided. This device includes a content addressable memory and a segmented unit, wherein the content addressable memory has a plurality of cells arranged in an array and a search line connected between each pair of adjacent cells. Moreover, a first segmented unit is connected between the cells to divide the cells into a plurality of segments to search and between a pair of the adjacent segments to cut off the search lines between the pair of the adjacent segments. Because the circuit of this device is divided into a plurality of segments to search, the circuit of the search line driver need not be modified. As a result, this circuit device can diminish the loading capacitance of the search line driver and reduce the power consumption with the segmented search method.
