Short answer. The data and instructions the CPU is using.
Can the CPU store much itself?
No, only a tiny amount.
Why memory?
| CPU processes, stores very little |
| Input waits in memory |
| Results wait before output |
Remember
| CPU works, memory holds |
Can the CPU work without memory? No. Memory holds what the CPU is using. The CPU is fast but stores very little. Input waits in memory. Results wait there before output. Remember this. The CPU works, memory holds.
