Abstract
Disclosed in the present invention is an ultra-compact CAM array based on a single MTJ and an operating method thereof. The CAM array comprises an M*N CAM core for storing contents, additional reference rows for storing '0' and “1” and reference columns for storing “0” and “1”, a row decoder, a column decoder, transmission gates ENs, write drivers WDs, search current sources Is and two-stage detection amplifiers. The present invention utilizes 1T-1MTJ cells to construct the CAM array, and combines the advantages of the MTJ and CMOS. While ensuring search energy efficiency, a unique structure of the MTJ is utilized to implement a less area overhead and a lower search delay compared with a traditional CMOS-based CAM, and non-volatility is achieved.
