The LANCAM 1ST family consists of high density contentaddressable memories (CAMs) in a variety of depths. Like the other LANCAM series from MUSIC Semiconductors, the LANCAM 1ST is ideal for time critical applications requiring intensive list processing.

Content-addressable memories, also known as associative  memories, operate in the converse way to random access memories (RAM). In RAM, the input to the device 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 LANCAM 1ST is ideal for address filtering and translation applications in LAN switches and routers. The LANCAM 1ST is also well suited to encryption, data caches, and branch tables.
