Time Required to find an item stored in memory can be reduced considerably if stored data can be identified for access by content of data rather than by an address
please explain me how...?

this is written in the topic "associative memory" in the computer system architecture book by mano
somebody explain how...
rcgldr said:A content addressable memory (fully associative) has one comparator for each memory cell. When a value is to be searched for within the content addressable memory, all of the memory cells are read and compared at the same time (in parallel), in one memory + one compare cycle, and then if there is a match, the address is returned based on which cell had the match.
In a normal search for a value in memory only one memory cell is read and compared at a time. In the simplest implementation, every cell in the memory would have to be read and compared one at a time until a match was found or all memory cells were read (and no match found).
In some situations, multiple matches are possible. The comparator outputs from the CAM go into an array of bits, and one of the matches will be converted into an address. This could be repeated to obtain a list of addresses if needed.

Some older computers used a fully associative cache. In the computer tape peripheral industry, content addressable memories (fully associative) are used for the sliding window type (LZ1 / LZ77) compression schemes.phinds said:I never heard of such a thing. Do they exist in the real world or is this just a math model?

Association memory works by connecting and linking related items in the brain. When trying to find an item stored in memory, the brain searches for associations or connections that can lead to the retrieval of the desired item.
Yes, association memory can help with time reduction in finding a stored item. By utilizing associations, the brain can narrow down the search and retrieve the desired item more quickly, saving time and effort.
Some techniques to improve association memory include creating vivid mental images, using mnemonic devices, and practicing retrieval of information through repetition and review.
Time can affect the retrieval of stored items in memory in several ways. Forgetting can occur over time, making it harder to retrieve the desired item. However, with proper encoding and storage techniques, time can also strengthen the association memory and make it easier to find the stored item.
Yes, external cues or triggers can aid in the retrieval of stored items in memory. These cues can be anything from smells, sounds, or objects that are associated with the stored item and can help trigger the memory and make it easier to retrieve the desired item.
