Cosa (chi) è content addressable memory - definizione

SPECIAL TYPE OF COMPUTER MEMORY USED IN CERTAIN VERY-HIGH-SPEED SEARCHING APPLICATIONS

  • CMOS binary CAM Cell consisting of a 6T SRAM cell plus 4 comparison transistors. When the data on the search lines (SL) differs from the data stored in the cell through the bit lines (BL), the match line (ML) will be pulled low to indicate a mismatch. If none of the cells on a match line indicate a mismatched bit, the match line will remain high at the precharge level to indicate a word match. Both search lines can be held at logic '0' as a don't care search condition. Search lines and bit lines can be merged into a single pair of data lines.
  • Content addressable memory
  • CMOS Ternary CAM cell consisting of two 6T SRAM cells plus 4 comparison transistors. Normally opposite logic levels, either '0' and '1' or '1' and '0' will be stored in the two cells. For a don't care condition '0' will be stored in both cells so that the match line ML will not be pulled low for any combination of search line (SL) data.

Content-addressable memory         
Content-addressable memory (CAM) is a special type of computer memory used in certain very-high-speed searching applications. It is also known as associative memory or associative storage and compares input search data against a table of stored data, and returns the address of matching data.
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. (1995-02-16)

DATA STORAGE MECHANISM
Content addressed storage; Content addressable storage; Content-addressed
Content-addressable storage (CAS), also referred to as content-addressed storage or fixed-content storage, is a way to store information so it can be retrieved based on its content, not its name or location. It has been used for high-speed storage and retrieval of fixed content, such as documents stored for compliance with government regulations.

Content-addressable memory

Content-addressable memory (CAM) is a special type of computer memory used in certain very-high-speed searching applications. It is also known as associative memory or associative storage and compares input search data against a table of stored data, and returns the address of matching data.

CAM is frequently used in networking devices where it speeds up forwarding information base and routing table operations. This kind of associative memory is also used in cache memory. In associative cache memory, both address and content is stored side by side. When the address matches, the corresponding content is fetched from cache memory.
