Music CAM’s are developed around Static RAM Cells, the advantage of using static RAM is that no time is lost in refreshing the memory cells (as opposed to Dynamic RAM). The comparand (value to be searched) is presented on all the bitlines at the same time, the result (matching locations) is presented to a priority encoder which takes care of resolving the highest priority matching location. By searching all bit locations in parallel a low latency search operation is guaranteed. CAM search cycles are fully predictable concerning search time, a 35 ns second device completes the search in 35ns. The results become available directly after the cycle completes, no pipelining or buffering schemes are implemented. ![]() MUSIC CAM and HARRP devices are at least 64 bit wide offering true binary searches. Some devices have the capability to do ternary compares using 2 bits to store data and mask information. We offer a large range of CAM depths starting from a 1K deep through 8K deep by 64 bit wide device up to 2K deep by 80 bit wide. |
