What is burst?mode operation (in the context of a cache memory)?
What will be an ideal response?
Burst?mode operation ties together two features of cache and DRAM. Cache memory uses lines as the minimum
transfer size between cache and memory (the idea is that data items should fit in a single cache line). Typically, a
line is 32 bytes, which means that 32 bytes have to be loaded following a miss.
Some DRAM’s have a burst mode operation where an address is used to make an access and then successive
words can be read without providing a new address because the memory has an internal sequencer. This feature
allows the memory to supply a burst of data during a cache refill.
