fun with a RAM

The following circuit is intended as a simple illustration of how to interface peripheral `hardware` with a RAM. Random Access Memories (RAMs) are usually used in microprocessor appli-cations where the data to be stored must be changed or modified easily. Static RAMs, like the one used in this circuit, use the inherent storage capa-bility of a bistable device such as the flip-flop. A static RAM will store information until the information is changed or until the power to the device is switched off.
