Associative memory is also known as content addressable memory (CAM) or associative storage or associative array. It is a special type of memory that is optimized for performing searches through data, as opposed to providing a simple direct access to the data based on the address.
Associative memory of conventional semiconductor memory (usually RAM) with added comparison circuity that enables a search operation to complete in a single clock cycle. It is a hardware search engine, a special type of computer memory used in certain very high searching applications.
Applications of Associative memory :-
- It can be only used in memory allocation format.
- It is widely used in the database management systems, etc.
Advantages of Associative memory :-
- It is used where search time needs to be less or short.
- It is suitable for parallel searches.
- It is often used to speedup databases.
- It is used in page tables used by the virtual memory and used in neural networks.
Disadvantages of Associative memory :-
- It is more expensive than RAM.
- Each cell must have storage capability and logical circuits for matching its content with external argument.
