Dynamic random-access memory: History & Technology

Dynamic random-access memory (dynamic RAM or DRAM) is a type of random-access semiconductor memory that stores each bit of data in a memory cell. A DRAM memory cell usually consists of a microscopic capacitor and a transistor, both typically based on metal–oxide–semiconductor (MOS) technology.
