DDR4 (Double Data Rate 4) SDRAM, is a type of computer memory (Random Access Memory or RAM) that is commonly used in modern computers, servers, and other computing devices. It is an upgraded version of DDR3 SDRAM, offering increased performance and efficiency.
Here are some key features and improvements of DDR4 SDRAM compared to its predecessor:
1. Increased Data Transfer Speed: DDR4 operates at higher data transfer speeds compared to DDR3. It achieves this by using a higher clock frequency and improved bus architecture. DDR4 memory modules typically have higher data transfer rates ranging from 2133 MHz to 3200 MHz and beyond.
2. Higher Memory Density: DDR4 allows for higher memory densities, meaning that more memory can be packed into a single module. This enables systems to have access to a larger amount of RAM, which is beneficial for memory-intensive tasks and running multiple applications simultaneously.
3. Lower Power Consumption: DDR4 SDRAM operates at a lower voltage (1.2V) compared to DDR3 (1.5V). This reduction in voltage helps to decrease power consumption and heat generated, making DDR4 more energy-efficient.
4. Improved Error Correction: DDR4 introduces additional error correction features that enhance data integrity and reliability. This is particularly important in servers and mission-critical systems where data accuracy is crucial.
5. Backward Compatible: DDR4 modules are not compatible with DDR3 slots due to differences in the physical and electrical specifications. However, some motherboards and systems support both DDR3 and DDR4 modules.
DDR4 SDRAM has become the standard for most recent computer systems and offers improved performance, higher memory densities, and lower power consumption compared to its predecessors
