ABSTRACT: Content Addressable Memory
(CAM) is a type of memory used for high-speed search applications. Due to
parallel comparison feature, the CAM memory leads to large power consumption
which is caused by frequent pre-charge or discharge of match line. In this
paper, CAM for automatic charge balancing with self-control mechanism is proposed
to control the voltage swing of ML for reducing the power consumption of CAM.
Another technique to reduce the power dissipation is to use MSML, it combines
the master-slave architecture with charge minimization technique. Unlike the
conventional design, only one match line (ML) is used, whereas in Master-Slave
Match Line (MSML) one master ML and several slave MLs are used to reduce the
power dissipation in CAM caused by match lines (MLs). Theoretically, the match
line (ML) reduces the power consumption up to 50% which is independent of
search and match case. The simulation results using Cadence tool of MSML show
the reduced power consumption in CAM and modified CAM cell.
