Dynamic RAM Chip
Dynamic random access memories (DRAMs) are the simplest and hence the smallest, of all semiconductors memories, containing only one transistor and one capacitor per cell. For that reason they are the most widely used memory type wherever high density storage is needed, most obviously as the main memory in all types of computers. Static RAMs are faster; by their much larger cell size (which holds up to six transistors) keeps their densities one generation behind those that DRAMs can offer.
