Static Random-Access Memory Dynamic Random-Access Memory
COMPUTER ORGANIZATION AND ARCHITECTURE DESIGNING FOR PERFORMANCE NINTH EDITION
RAM technology is divided into two technologies: dynamic and
static. A dynamic RAM (DRAM) is made with cells that store data as charge on
capacitors. The presence or absence of charge in a capacitor is interpreted as a
binary 1 or 0. Because capacitors have a natural tendency to discharge, dynamic
RAMs require periodic charge refreshing to maintain data storage. The term
dynamic refers to this tendency of the stored charge to leak away, even with power
continuously applied.
