1. 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.
-
2. How to measure the data read and write speed of memory?
The read and write speed of memory is usually expressed in MB/s or GB/s, reflecting the amount of data it processes per second. The faster the speed, the higher the data transmission efficiency.
-
3. What is the memory hierarchy in a computer?
The computer memory hierarchy includes registers, cache, main memory (RAM), secondary storage (such as HDD or SSD), and external storage (such as tape, optical disk) from speed to capacity, and each level has different storage and access speeds.
-
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.
