1. What are the main types of memory?
Common memory types include random access memory (RAM), read-only memory (ROM), flash memory, hard disk drive (HDD), and solid-state drive (SSD).
-
2. 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.
-
3. How to extend the life of memory devices?
Measures such as regular data backup, avoiding excessive reading and writing of memory, ensuring proper temperature control, and preventing power fluctuations can help extend the life of memory.
