What is a key feature of DDR2 memory?

The key feature of DDR2 memory is that it is faster than its predecessor, DDR, while also using less power. DDR2 achieved higher speeds due to improvements in technology, allowing for a greater data transfer rate, which enhances overall performance in computing systems. Additionally, DDR2 operates at a lower voltage compared to DDR, which contributes to its efficiency in power usage. This combination of faster operation and reduced power consumption makes DDR2 memory a more advanced option compared to DDR. The advancements in DDR2 not only boost speed but also improve system performance without significantly increasing power demands, leading to overall better efficiency in modern computing environments.
