1.DMA may lead to cache coherency problems.
2.May lead to bus error interrupt, which arent easy to process.
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.
If by DMA you mean Direct Memory Access, nothing has replaced it.
DMA Direct Memory Access DMA transfers data directly from the drive to memory w/out involving the CPU.
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.
