GENERAL DESCRIPTION
The MU9C3480L LANCAM is a 256 x 64-bit Contentaddressable Memory (CAM), designed for address filtering applications in Local-area Network (LAN) bridges, routers, and switches needing a 3.3 volt CAM. The architecture of the LANCAM allows a network station list of any length to be searched in a single memory transaction. This device is also well-suited for other high-speed data search applications such as virtual memories, optical and magnetic disk caches, data base accelerators, data compressors, and image processors.

DISTINCTIVE CHARACTERISTICS
• Selectable faster operating mode with no wait states
   after a no-match
• Validity bits of entries are stored in the Status register
   after a read or move from memory operation
• Single cycle reset for Segment Control register
• Packaged in an industry-standard 44-pin PLCC
   package to be socket compatible with the MU9C5480L
   and MU9C1480L
• Single 3.3 Volt Supply for low power operation
• 256 x 64-bit CMOS Content-addressable Memory (CAM)
   with 16-bit I/O for compatibility with the MU9C5480L
• Dual configuration register set (Control, Segment
   Control, Mask Register 1, Address Register, and
   Persistent Source and Destination) for rapid context
   switching
• Shiftable Comparand and Mask Register 2 to assist in
   proximate matching algorithms
• Increased flexibility of the patented CAM/RAM
   partitioning
• Added /MA and /MM output flags to enable faster
   system performance
• Readable Device ID
