Content addressable memory (CAM) devices having CAM array blocks therein that perform pipelined and interleaved search, write and read operations and methods of operating same

摘要

Content addressable memory (CAM) devices according to embodiments of the present invention conserve match line and bit line power when CAM array blocks therein are searched. These CAM array blocks are searched in a pipelined segment-to-segment manner to increase search speed. The pipelined search operations may also be interleaved with write and read operations in an efficient manner that reduces the occurrence of pipeline bubbles.
