1. What is the difference between RAM and ROM?
RAM is volatile storage and is used to temporarily store data; while ROM is non-volatile storage, which can still save data after the device is turned off, and is usually used to store unchangeable data such as system startup programs.
-
2. What is flash memory and what are the common types of flash memory?
Flash memory is a non-volatile memory used to store data, and the data will not be lost even if the device is powered off. Common types are NAND and NOR flash memory, which are mainly used in USB flash drives, SSDs, memory cards, etc.

3. What are volatile and non-volatile memory?
Volatile memory loses data when power is off, such as RAM; non-volatile memory retains data after power is off, such as ROM and flash memory.

4. What is High Bandwidth Memory (HBM) and what are its advantages?
HBM is a high-bandwidth, low-latency memory technology commonly used in graphics cards and AI accelerators that can handle a large number of parallel computing tasks. HBM's stacked architecture makes it take up less space and more efficient, making it an ideal choice for big data and high-performance computing applications.
