Dynamic random access memory (DRAM) is a type of random access memory, which stores every bit of information in a different capacitor within an integrated circuit. Although, the capacitor can be either charged or discharged represented by two values of so-called as 0 and 1. However, even “non conducting” always leak a small piece of information, these capacitors will be slowly discharged and the corresponding entire data is vanished instead the capacitor charge is refreshed from time to time. Because of this refresh requirement, it is a dynamic memory as opposed to SRAM and other static memory. Moreover, the main memory in personal computer, desktop, laptop and workstation can be dynamic RAM (DRAM).

Unlike static RAM (SRAM), it needs to have its storage cells refreshed or given a new electronic charge every few milli seconds. There is no need to refresh Static RAM because it operates on the principles of moving current, which is switched in one of the two directions one of the two directions rather than a storage cell, which holds a charge in place. The main advantage of DRAM is its simple structure includes one transistor and a capacitor needed per bit, in contrast to the four to six transistors in SRAM. It facilities you to reach very high densities with huge memory, because it loses its data quickly due to sudden power failure. In addition, the transistors and capacitors are portable in nature and so that billions can fit on a single memory chip. Dynamic random access memory is produced as integrated circuit (ICs) bonded and mounted into plastic packages with metal pins to control signals and buses.

Further, a variety of other RAM interfaces to the system exists including EDO RAM and SDRAM. The majority of errors in DRAM chips occur due to background radiation, chiefly neutrons from cosmic ray secondaries, which may alter the contents of one or more memory cells or interference with the circuitry used to read or write them. Some standard module types are DRAM chip (Integrated Circuit), DRAM (memory) modules, stacked vs Non Stacked RAM Modules. However, dynamic memory is only specified and guaranteed to retain its contents are supplied with power and refreshed every short span of time, the memory cell capacitors usually retain their values for longer and at particularly lower temperatures.
