Design of Memristor Based CAM for High Speed, Low Power Search Applications

Content addressable memory (CAM), Memristor based CAM (MCAM), modeling of Memristor.

The content addressable memory (CAM) is a type of memory in which it compares the input search data against the data stored in the memory and returns the address of the memory. The difference between the SRAM and the CAM is that in SRAM the input is given as address and it returns the data stored but in the CAM the input is given as the data and it returns the address of the data stored. The conventional CAM contains SRAM to store the data and the matching circuitry for the search operation. Due to its parallel search mechanism it consumes more power and it is one of the major design challenge when designing the CAM. This paper provides a new approach to the design and modeling of CAM called the Memristor CAM which uses a Memristor and MOS devices to form memory architecture. The Memristor has non-volatile characteristics and provides a new approach towards the power management by disabling the CAM blocks without the loss of the stored data.
