A scheme for ultra-low power content addressable memory based on a ripple search is disclosed. In one embodiment, a system for content addressable memory (CAM), includes a storage unit for storing a portion of content data, and a match module for comparing the portion of the content data with a respective portion of search data received by the match module. The match module includes a first static logic gate associated with a first half of the storage unit storing a sub-portion of the portion of the content data, and a second static logic gate associated with a second half of the storage unit. The first static logic gate forwards a signal for disabling the second static logic gate if the sub-portion of the portion of the content data does not match with a respective sub-portion of the portion of the search data.
