Power Gating and Parity Bit Techniques for Low Power CAM
Main Article Content
Abstract
Content addressable memory is one of the special type of memory device used to high speed searching devices. Main feature of CAM
is it can search entire memory in a single clock cycle. And CAM is the faster search application by comparing RAM. CAM requires more power
consumption because of parallel match line comparison. High speed and low power Match-line sense amplifiers are very highly sought-after in
CAM designs. A parity bit technique is best for to reduce area and power consumption. Furthermore, in this paper we introduced gated-power
match-line sensing technique to reduce average power consumption.
Keywords: Content addressable memory (CAM), Search-line (SL), Match-line (ML), ML sense amplifier.
