NVMe Aims For Annual Spec Updates

By Gary Hilson, EETimes | September 19, 2025

New features and engineering change notices (ECNs) recently announced by NVM Express, Inc. encompass 11 NVMe specifications, including the base specification. In a briefing with EE Times, Mike Allison, chair of the NVMe Errata Task Group, said the updates are based on input from the organization’s membership, which has exceeded 1,000 participants.

He said that since the last update, eight proposals have been ratified, with eight ECNs clarifying specifications based on member input. Still, ultimately, only a few specifications were changed as a result of the technical proposals. 

On the security front, there’s now the ability to do cryptographic erase sanitization on individual namespaces rather than having to impact the entire NVM subsystem. “You can go into an individual namespace and say sanitize,” Allison said. 

A configurable device personality feature also enhances security, he said. It enables a host to securely modify the NVM subsystem configuration, which makes it easier for device providers to manage inventory, especially for vendors who don’t have as many SKUs. “It’s a way to limit the number of SKUs by vendors and help the whole manufacturing chain.”
