| Popis: | Content addressable memory (CAM) is widely used in the systems with the need of parallel search. The testing of CAM is more difficult than that of random access memory (RAM) due to the complicated function of CAM. Similar to the testing of RAM, the testing of CAM should cover the cell array and peripheral circuits. In this paper, we propose a March-like test, March-PCL, for detecting the stuck-open faults (SOFs) of the priority address encoder of CAMs. As the best of our knowledge, this is the first word to discuss the testing of SOFs of the priority address encoder of CAMs. The March-PCL requires 4N Write and 4N Compare operations to cover 100% SOFs. |
