The Circuitry of Computer Memory
BACKGROUND A computer is useful because it is a device that can not only execute instructions but can also store and retrieve information along the way to aid in the execution of such instructions. Like everything else in an electronic computer, the component that handles this functionality (the memory subsystem) is made up of electronic circuits. In this article, I will like to share a high-level overview of what this circuitry looks like and how it operates. Electronic circuits are built from basic elements called logic gates (AND, OR, NAND, etc). It is advisable that the reader know these basic elements and understands how they operate as this will make it easier to follow along with the material. This Wikipedia article is a start. ...
