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.

Associative Memory is a memory chip in which each bit position can be compared. In this, the content is compared in each bit cell which allows very fast table lookup. It looks up a storage location by its contents. Associative memory is managed by both the operating system and hardware. These chips have less storage capacity than regular memory chips.
Cache memory is a high-speed memory which is used to reduce the access time for data. Cache memory stores the copies of original data that has been recently used. Cache memory is fully managed by the hardware. Cache memory has a bounded size.

What is the difference between cache-memory and primary-memory?
Cache memory is smaller and quicker, primary memory larger and slower.
What are the difference among direct mapping associative mapping and set associative mapping?
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
What is the difference between cache memory disk cache?
memory cache is on memory RAM, disk Cache is on the hard drive. They make things to get faster. For instance Google Earth use this disk cache to show you offline images.
Three cache mapping techniques?
Three types of mapping procedures are there? (1) Associative Mapping-The fastest and most flexible cache organizations uses associative mapping. The associative memory stores both the address and content of memory word. This permits any location in catche to store word in main memory. (2) Direct Mapping-Associative memories are expesive compared to RAM's because of added logic associated with each cell. (3) Set Associative Mapping-It is a more general method that includes pure associative and direct mapping as special case. It is an improvement over the direct mapping organization in that each word of cache can store two or more words of memory under the same index address. Each data word is stored together with its tag and the number of tag data items in one word of cache is said to form a set. With Regards Veer Thakur Chandigarh

Mapping function between cache lines and main memory block?
I didn't quite understand your question but I'll answer you anyways :P.. It's known that the main memory is much larger that the cache memory , and we need to transfer a block of instructions to the cache memory to be frequently used by the processor to improve performance and reduce time spent in fetching instructions or data ( dealing with cache memory is much faster than RAM ). for example lets say that a main memory has a 128 data blocks and you need to place them in the cache memory which consists of 32 data blocks? then you have to have sort of technique to place them or MAPPING FUNCTION. And there are plenty of 'em (four mapping techniques as far as i know) i will just mention them without getting into details: Direct mapping , fully-associative, set-associative and n-way set associative. if you need more details just ask. greetings Can you please provide some help over Direct mapping , fully-associative, set-associative and n-way set associative Thanx
What is the difference between cache memory and primary memory?
they are both different so stop asking dumb questions
Why is cache memory more expensive than hard disk?
as the cache memory is mory faster than RAM or hard disk ,but the main reason is that the cache memory has comparator and storage medium at the same time, the comparator checks if the address of the value being accessed is in the associative memory(a part of cache)or not, and the ordinary memory(another part of cache)has the data....
What the difference among direct mapping associative mapping and autoassociative mapping?
Direct mappingA given Main Memory block can be mapped to one and only one Cache Memory line.It is Simple, Inexpensive, fastIt lacks mapping flexibilityAssociative mappingA block in the Main Memory can be mapped to any line in the Cache Memory available (not already occupied)It is slow, expensiveIt has mapping flexibility
Diagram to show the address mapping of RAM and Cache?
consider a RAM of 64 words with a size of 16 bits.Assume that this memory have a cache memory of 8 Blocks with block size of 32 bits.Draw a diagram to show the address mapping of RAM and Cache, if 4-way set associative memory scheme is used.
What are the type of cache memory?
There are different type of cache memory: processor cache memory, cache memory ram,1 cache memory l2, cache memory, CPU cache memory, disk cache memory, hard disk cache, cache memory motherboard.
What is assosciative mapped cache?
An associative cache is a cache that has 1 or more extra slots for each place in memory. So if two pieces of memory map to the same place in cache, you can write both entries. In this case, you will need a cache replacement policy to determine which gets evicted first when it's full and new data arrives.
