What is Persistent Memory?

The term persistent memory is used to describe technologies which allow programs to access data as memory, directly byte- addressable, while the contents are non- volatile, preserved across power cycles. It has aspects that are like memory, and aspects that are like storage, but it doesn’t typically replace either memory or storage. Instead, persistent memory is a third tier, used in conjunction with memory and storage. Systems containing persistent memory can outperform legacy configurations, providing faster start-up times, faster access to large in-memory datasets, and often improved total cost of ownership.
