DDR4/5 Insights

What is DDR4/5?

DDR4 SDRAM (Double Data Rate 4 Synchronous Dynamic Random-Access Memory) is a type of synchronous dynamic random-access memory with a high bandwidth interface. It is primarily used as main system memory in computers to store data and program code that the CPU is actively using. DDR4 offers higher module density and lower voltage requirements compared to DDR3, resulting in improved performance and energy efficiency.
