Mail Boxes
The Eprom is a basic, mechanical device which can be considered simply as a block of
"mail boxes", each holding a message. Each "box" is numbered consecutively. At one end
of the block of "boxes" is a slot and by posting the Address or LOCATION NUMBER of a
particular "box" into this slot you will make its message contents appear from the output
slot at the other end of the block.
You can read the contents of ANY "box" in this manner if you know its number.
