Title : A High Speed Low Power CAM with Power-Gated Match Line Sensing Using Keyword-Based Search Method

Author Name : Shanmugapriya M, Shenbagapariya M

Synopsis :

The design of high speed Content Addressable Memory (CAM) offers high-speed search function in a single clock cycle. Content Addressable Memory (CAM) is a type of solid-state memory in which data are accessed by their contents rather than physical locations. It receives input search data, i.e., a search word, and returns the address of a similar word that is stored in its data-bank. In previous system, we introduced a parity bit that leads to sensing delay and increase the power consumption. It takes more time to sense the match line. In this paper, we used keyword based search method. The concept of this method is to pre-compare several bits of the match line in advance. Through the mechanism of the keyword search pre-comparison scheme, it can decide that whether the other bits would be compared or not and which reduces even more sensing delay and reduce the power.
