Since there has been all this talk about CAMs, I am taking the liberty
of including a press release on my company's product. (if I get flamed
for this then I won't do it anymore)

"The industry's first VLSI CAM is now available from AMD. The
high-performance Am99C10, with a capacity of 256 words and a
user-programmable word width of 16 bits or 48 bits, features a totally
new concept in memory devices -- memory with built-in logic on every
cell. 

The Am99C10 CAM is composed of 256 words, each consisting of a 48-bit
register and a 48-bit maskable comparator. Data presented to the CAM
is simultaneously compared to all 256 addresses in a single 100 ns
cycle. When a match occurs, the on-chip priority encoder generates a
match-word address identifying the location of the data in the CAM. If
multiple matches occur, the encoder generates the lowest matched
address. Any or all bits of the comparand value can be selectively
masked, allowing for comparison on only a portion of the data word. 

The CAM is ideal for use in high-speed Ethernet and FDDI local area
networks, and in bridging applications where it can operate as an
address filter and perform the network address look-up function. The
Am99C10 CAM also has applications in database machines, file servers,
image processing, and neural networks. 

For more information, contact Barbara Kern, (408) 982-7451."

Please note the following disclaimers:

* I am not an official spokesman for the company.
* Any mistakes made in the transcription are my fault.
* I know nothing about this device besides what you just read.
  I work in another group entirely and am merely posting this as
  a service to the readers of this group. Please contact the
  listed person if you have any questions or comments.
