What is the notable feature of the latest advancement in computer memory technology?

One notable feature of the latest advancement in computer memory technology is the development of non-volatile memory, such as 3D XPoint memory. This type of memory retains data even when the power is turned off, unlike traditional volatile memory like RAM. Non-volatile memory offers faster access times and higher storage capacities, making it ideal for use in applications where data persistence is crucial, such as in data centers and high-performance computing systems.
