GENERAL DESCRIPTION

The LANCAM consists of various depths of 64-bit Content Addressable Memories (CAMs), with a 16-bit wide interface.

DISTINCTIVE CHARACTERISTICS

? High density CMOS Content Addressable Memory (CAM)

? 1K (1480B), 2K (2480B) , 4K (4480B), 8K (8480B) words

? 64-bit per word memory organization

? 16-bit I/O

? Fast 50 ns compare speed

? Dual configuration register set for rapid context switching

? 16-bit CAM/RAM segments with MUSIC’s patented partitioning

? /MA and /MM output flags to enable faster system performance

? Readable Device ID

? Selectable faster operating mode with no wait states after a no-match

? Validity bit setting accessible from the Status register

? Single cycle reset for Segment Control register

? 3.3 Volt operation
