DRAM is extensively used as the main memory in virtually all computing devices, such as desktop and notebook computers. It is a type of RAM (random access memory), and is the most widely used semiconductor memory used in current generation computers, offering multiple advantages, such as structural simplicity, very high packing densities (number of bytes that can be stored per unit of chip area), low power consumption, and sufficiently high data read/write speeds. Several types of DRAM are presently available for deployment on notebook computers. With rapid developments in semiconductor memory technology, DRAM has demonstrated significant performance enhancements, resulting in a considerable overall performance improvement for the computing segment.
