What is DRAM (Dynamic random access memory)?

Dynamic random-access memory is a sort of arbitrary access semiconductor memory that saves every bit of information in a memory cell comprise of a small capacitor and a transistor, both typically dependent on metal-oxide-semiconductor (MOS) method. DRAM ordinarily takes the form of an integrated circuit chip, which can comprise of many of DRAM memory cells. DRAM chips are generally utilized in advanced electronics where minimal expense and high-limit PC memory is needed.
