Intel Optane

Intel Optane was a family of nonvolatile memory products that Intel and Micron co-developed to address rowhammer.¹ It was cancelled as a product in 2022.²

The underlying technology was called 3D XPoint and used a bulk form of phase-change memory based on chalcogenides (as opposed to filament-based phase-change memories, which were predominant prior)

Micron marketed its own products based on 3D XPoint as QuantX.
