Inside Computer Memory

About this quiz

What this quiz asks

1. When you are playing a game on your computer, which type of memory holds the temporary data that disappears once you turn the power off?
2. Look at the image of the memory module. Which component is responsible for storing bits of data as electrical charges that need to be refreshed constantly?
3. If a computer's memory is filled with data, what happens to the electrical charges in volatile memory if the power supply is suddenly cut?
4. Imagine a system that uses volatile memory for speed. Based on the image, why is this memory type used for running active programs instead of long-term storage?
5. Which type of storage device retains data even when the power is turned off, making it essential for long-term file saving?
6. Look at the visual showing data being saved onto a medium. Which of these materials is most commonly used in modern non-volatile flash storage to trap electrons?
7. If a computer needs to store photos that remain saved after the computer is shut down, which component architecture should it utilize?
8. Considering the physical structure of a storage cell, what happens to the electrical state when data is written to a non-volatile flash cell?
9. In semiconductor architecture, which fundamental electronic component acts as a microscopic switch to control the flow of electricity in memory cells?
10. Looking at this grid, which component is primarily responsible for storing an electrical charge to represent a single bit of data in DRAM?
11. In the arrangement of a memory chip, what is the primary purpose of the word line and bit line grid pattern shown here?
12. Based on the density of the transistors shown in this cross-section, why is the 'scaling' of semiconductor architecture so critical for modern memory?
13. Which type of computer memory is positioned at the very top of the hierarchy because it is the fastest but also the smallest in capacity?
14. Looking at the memory pyramid, which level serves as the primary bridge between the fast processor and the slow long-term storage?
15. If a computer system needs to access data that is not currently in the CPU cache or RAM, where does it look next in the Memory Hierarchy?
16. Why does the Memory Hierarchy use multiple layers of memory instead of just one single, large, and fast memory type for everything?
17. A memristor is a unique electronic component that acts like a memory-resistor. Based on the visual, which property allows it to 'remember' its state even when power is turned off?
18. In the context of Emerging Memristor Tech, what does the 'hysteresis loop' shown in the graph signify about how data is stored?
19. Look at the image showing a cross-point array of memristors. Why is this structure considered a breakthrough for future computer architecture?
20. Based on the visual representation of an 'Artificial Synapse', how does Emerging Memristor Tech mimic the human brain?
21. Phase-change materials used in memory change their physical state to store data. Looking at the illustration, which state represents the high-resistance '0' bit?
22. Based on the visual of the atomic grid, what process must occur to transition the material from a disordered state to an ordered crystalline state to store a '1' bit?
23. Observe the graph showing resistance levels over time. Which material state is being created when the current pulse causes a sudden, sharp drop in resistance?
24. If the image shows a laser pulse hitting a Phase-Change Material, what is the most likely outcome if the pulse is extremely short and intense?
