mixed NVMs in Messier system

Open diweshibm opened this issue 4 years ago • 2 comments

Hi, I am not sure if this is the right place to ask this question, sorry for spamming over here. I have got a basic query regarding the use case of Messier system. Can I have different types of NVMs in a single DIMM? For example, suppose I want to have one PCM (phase-change memory) and one memristor sitting next to each other. Is this possible? I was looking into the diagram in page 7 here, but I am not sure if inside a bank I can have two different types of NMVs. https://prod-ng.sandia.gov/techlib-noauth/access-control.cgi/2017/171830.pdf

@amroawad2 - did you want to answer this question? We might want to transfer to SST-Elements.

@nmhamster sure. Currently the timing parameters are used for the whole DIMM not per bank. However, if you are talking about NVDIMMS-* standards, modeling them can be done by using Messier component along with another backend, or possibly change the cache model in Messier to reflect the timing of another technology in case of hybrid DIMM models. I hope this answers your question, but if you shed more light on what you are trying to do I can possibly provide more help.
