Access time(T) = HXAM + (1-H)(AM + PT)
where H = hit rate, AM = Associative Mem ref time, PT = Page Table access time.
its also called 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, associative storage, or associative array
The formula to calculate the average memory access time in a computer system is: Average Memory Access Time Hit Time Miss Rate x Miss Penalty
A two-way set-associative cache improves memory access efficiency by allowing each cache set to store data from two different memory locations. This reduces the likelihood of cache conflicts and increases the chances of finding the requested data in the cache, leading to faster access times compared to caches with fewer associativity levels.
i need de diagram on associative memory..

Associative Memory.
in memory allocation formates only we are using this associative memory. an it is widely used in database management systems etc................ If we want to get the information about this we will give the total information about the whole data.
The differences among direct mapping and set-associative mapping :Direct mapping : Each line in main memory maps onto a single cache line.Set-associative : Each line in main memory maps onto a small (collection) set of cache line.Direct mapping : A memory block is mapped into a unique cache line, depending on the memory address of the respective block.Set-associative : A memory block is mapped into any of the line of a set. The set is determined by the memory address, but the line inside the set can be any one.dont knowyet

Memory access time is corresponding to the time interval between the read/write request and the availability of the data. cycle time representing the minimum time interval between two successive accesses
There is no term "associated memory" in any tech dictionary. Cache memory is the L1 and L2 you see when you buy a PC. L1 cache is a small memory for the CPU to use. Instead of going all the way back to RAM get informaton is has some information stored in the cache so it can get to it faster. So if you buy a computer then look at the size of the cache. The larger the cache the faster the system will run since the CPU will be able to access that much more faster.
There are two types of memory access. 1- uniform memory access (uma) 2- non-uniform memory access (numa)
