Abstract
A content addressable memory (CAM) device having any number of rows, each of the rows including a match line connected to a plurality of CAM cells, a match line detector circuit, and an incremental match line charge circuit. The detector circuit generates a feedback signal based on a detected match line voltage. The charge circuit partially pre-charges the match line to an intermediate voltage during a pre-charge phase of a compare operation, and then selectively charges the match line higher towards a supply voltage in response to the feedback signal.
