Abstract
A time-division memory control device controls a content addressable memory (CAM) cell array of a CAM in a time-division manner and thereby reduces a peak current and mitigates electromigration and voltage variation problems. The time-division memory control device includes a time-division controller and a peripheral circuit. In a search and compare operation, the time-division controller outputs a first group of control signals at a first time point according to a system clock, and outputs a second group of control signals at a second time point later than the first time point. The peripheral circuit includes: a first group of circuits cooperating with a first group of CAM cells of the CAM cell array according to the first group of control signals; and a second group of circuits cooperating with a second group of CAM cells of the CAM cell array according to the second group of control signals.
