RANDOM-ACCESS-MEMORY (RAM) (16 WORDS OF 4 BITS)
Objectives of this experiment:
The purpose of this experiment is to demonstrate how you can WRITE (store) digital data into the semiconductor memory and how to READ (retrieve) this data from the memory, using IC-7489, at any time later on. RAM is a volatile memory. RAM is a semiconductor memory into which digital data can be written into, and then read out again. Any location in RAM is accessible without regard to any other location. It is organised as a 16 words of 4-bits scratch pad. You can store any number, from 0 to 5, into any sequence of location. This experiment is a MUST to understand how computers store digital information, and how we can read this stored information at any time we want afterwards.
