1. What is the difference between cache and RAM?
Cache is a high-speed memory between the CPU and the main memory, which is used to temporarily store data and instructions commonly used by the CPU to speed up the system. RAM is the main storage of the system, which is used to store data for applications and operating systems.
-
2. How to choose the right memory type?
When choosing a memory type, you need to consider speed, capacity, durability and cost according to application requirements. For example, SSD is suitable for data that needs to be accessed quickly, HDD is suitable for large-capacity data storage, and RAM is suitable for high-speed computing.

3. What is ECC memory?
ECC (error correction code) memory detects and corrects single-bit errors in stored data, improving the reliability of memory and is commonly used in servers and data centers.
-
4. Why is the DRAM refresh rate important?
DRAM needs to be refreshed regularly to maintain data. The refresh rate affects the power consumption and speed of the memory. The higher the refresh rate, the faster the memory responds, but it also increases power consumption.
