No, a cache memory is often used to store data that has been needed recently on grounds that it will be faster to access when/if it is needed again.
When data that is requested is contained in the cache you have a cache hit, and when you have to retrieve it from the hard drive (or where ever its original storage was) again it is called a cache miss. Retrieving data from the hard drive is slower than retrieving it from the cache.
A cache hit occurs when the requested data is found in the cache memory, while a cache miss occurs when the data is not found in the cache and needs to be retrieved from the main memory. One can determine whether a cache hit or miss has occurred by checking if the requested data is present in the cache memory.
Memory cache stores frequently used instructions and data on a computer. Cache memory is stored on a memory chip in an area of the RAM.
The miss penalty in cache is calculated by determining the time it takes to access data from the main memory when a cache miss occurs. This time includes the latency of fetching the data from the main memory and loading it into the cache. The miss penalty is the additional time required when data is not found in the cache and needs to be retrieved from the main memory.
A direct mapped cache assigns each block of memory to a specific location in the cache. With 4-word blocks, each block is stored in a specific cache line based on its memory address. This means that each block of memory can only be stored in one specific location in the cache, making it easy to determine where to look for a specific block of memory.
In cache memory management, write allocate means that data is brought into the cache before writing to it, while no write allocate means that data is written directly to the main memory without being brought into the cache first.
I think that's Vista's ReadyBoost technology.
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.

No cache memory is not visible.....
Register memory are smaller in size than cache memory and registers are faster than cache..Cache memory store the frequently used data from main memory..
sram is used for cache for cache memory.
The maximum size of a cache memory is theoretically equal to the amount of primary memory(RAM).Like Cache only memory architecture where the whole memory space is filled up with the cache only.
Cache Memory is needed because Hardware implements cache as a block of memory for temporary storage likely to be used again.
Cache memory is smaller and quicker, primary memory larger and slower.
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.
l1 cache l2 cache
cache memory is neither main memory nor second memory. DDR's are Main memory and Disk is second memory.
