Chapter 4. BUFFER MEMORY CONFIGURATION AND FUNCTIONS

4.2 Functions of Buffer Memory

Each address in the buffer memory occupies one word and it is represented with 16 bits.

In the 16 bits which compose an address, every bit can be set to either “1” when it should be turned On or “0” when Off in order to implement the function of each bit.
