1. 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.
-
2. What is embedded memory?
Embedded memory is a memory integrated into an electronic system for real-time data processing and program execution of the device. It is commonly found in microcontrollers, mobile devices, and embedded systems.
-
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. What is virtual memory and how does it work?
Virtual memory is a technology that uses hard disk space as memory, allowing the system to use hard disk space to expand memory when physical RAM is insufficient, improving the system's multitasking capabilities.
