Design of a Low Leakage, Low Power and High Performance Search and Read Memory Using CAM and SRAM
Anup Dandapat, D. Kayal, Debdeep Mukhopadhyay · Journal of Low Power Electronics · 2008
A low leakage, low power and high speed memory has been developed using a combination of content addressable memory (CAM) and static random access memory (SRAM) in 150 nm node technology and with a power supply of 1 volt. Data search operation is done by using CAM while SRAMs are used as data storage cells. Data read operation is performed through a read circuit that is controlled by the search result of CAM cells. A priority checker has been incorporated into the CAM cells to make the search operation more precise.
