content addressable memory
(CAM, or "associative memory") A kind of storage device which includes
comparison logic with each bit of storage. A data value is broadcast to all
words of storage and compared with the values there. Words which match are
flagged in some way. Subsequent operations can then work on flagged words, e.g.
read them out one at a time or write to certain bit positions in all of them. A
CAM can thus operate as a data parallel (SIMD) processor.
CAMs are often used in caches and memory management units.
