Period

This type of IC made and presumably used in 1970s- early 1980s, and possibly later.

Canada

Part of a collection of early solid state devices assembled by the donor and his father during their careers as electronics technicians. (ref. 1)

Function

Enables data to be stored and retrieved directly to specific locations as long as internal capacitors are charged and discharged regularly.

Technical

Examples of early dynamic RAM chips, the most common form of RAM. In this form, Each cell has a charge or lack of charge held in something similar to an electrical capacitor. A transistor acts as a gate in determining whether the value in the capacitor can be read or written. It is typically the quickest RAM is the most cost effective, and has the highest density since it requires only one transistor per memory cell. It must be refreshed approx. every 10 m/s because the internal capacitors self-discharge quickly. Dynamic RAMs (DRAMS) typically have a slower access speed than other types of RAM. (ref. 3)
