Disclaimer: I work at Intel on Persistent Memory If you are asking just about the OS interfaces - you can already emulate persistent memory with DRAM [1], which allows you to play around with the programming model. There are also NVDIMM-N devices available on the market today that expose the same interface. IBM also has a product called Virtual Persistent Memory [2]. I expect that once CXL [3] becomes adopted, there will be more diversity in terms of Persistent Memory hardware vendors.
