1. What is memory and what does it do?
Memory is a computer component that stores data and instructions. It can be temporary (volatile storage) or permanent (non-volatile storage) and is used to support system operation and data storage.
-
2. 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.
-
3. What is double data rate (DDR) memory?
DDR memory is a RAM technology that can transmit data at both the rising and falling edges of the clock signal to increase the data transmission speed. There are multiple generations of DDR, such as DDR3, DDR4, DDR5, etc., each generation has higher speed and capacity and lower power consumption.
-
4. 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.
