general-scienceinformation-technology
- ADynamic RAM
- BEPROM
- CROM
- DStatic RAM

Dynamic RAM stores each bit as charge on a capacitor that leaks away, so it must be refreshed many times per second. Static RAM, EPROM and ROM do not require such refreshing. Hence dynamic RAM must be refreshed many times per second.
