1. Learn about all kinds of memory circuits and devices
2. Learn about latches and flip-flops, which are logic circuits that implement 1-bit memory
3. Trace through a latch to see how it uses feedback to actually store a 1 or a 0
4. Study some of the refinements of basic latches
5. Learn the standard notational symbols for latches and flip-flops
6. Learn what a register is
7. Differentiate between read-only memories (ROM) and read-write (RAM) memories
8. Study how RAM is organized and how it is used to store and retrieve "word" values
9. Review the basic terminology of memories and the sizes used
10. Study the memory cycle to see how RAM operates
11. Learn how ROMs can be implemented

Chapter 1 is the main prerequisite of this chapter. RAM and ROM use decoder circuits, which are introduced in Chapter 4.
