DescriptionThe MU9C4480A-90DC series consists of various depths of 64-bit Content Addressable Memories (CAMs), with a 16-bit wide interface.
CAMs, also known as associative memories, operate in the converse way to random access memories (RAM). In RAM, the input to the MU9C4480A-90DC is an address and the output is the data stored at that address. In CAM, the input is a data sample and the output is a flag to indicate a match and the address of the matching data. As a result, CAM searches large databases for matching data in a short, constant time period, no matter how many entries are in the database. The ability to search data words up to 64 bits wide allows large address spaces to be searched rapidly and efficiently. A patented architecture links each CAM entry to associated data and makes this data available for use after a successful compare operation.
The MUSIC LANCAMs are ideal for address filtering and translation applications in LAN switches and routers. The MU9C4480A-90DCs are also well suited to encryption, database accelerators, and image processing.
