Dynamic   random access memory (DRAM) is the most common kind of random access   memory (RAM) for personal computers and workstations. The network of   electrically-charged points in which a computer stores quickly   accessible data in the form of 0s and 1s is called memory. Random access   means that the PC processor can access any part of the memory directly   rather than having to proceed sequentially from some starting place.   DRAM is dynamic in that, unlike static RAM (SRAM), it needs to have its   storage cells refreshed or given a new electronic charge every few   milliseconds. Static RAM does not need refreshing because it operates on   the principle of moving current that is switched in oneof two   directions rather than a storage cell that holds a charge in place.   Static RAM is generally used for cache memory, which can be accessed   more quickly than DRAM.
