Summary:Content-addressable memory (CAM) is a special type of memory used in very high speed searching applications. CAM is used to search the entire memory in a single clock cycle. It is much faster than RAM in all search applications. Due to its parallel match line comparison, CAM requires more power consumption. Thus high speed and low power ML sense amplifiers are highly sought-after in CAM designs. A parity bit is introduced that leads to reduce area and power overhead. Furthermore, we propose an effective gated-power ML sensing technique to reduce the average power consumption.
