Which devices contain megaram (M-RAM/MRAM)?

[MarkZop]

I'm having a difficult time finding documentation on what Intel's M-RAM/Megaram is. In the RAM Megafunction User Guide, I see a reference to M-RAM. Upon searching Intel's site for the term 'M-RAM', I see they have a definition on it, in which they mention its support in the Arria devices. However, when I search the Arria product tables and data sheets, I don't see any reference to M-RAM/Megaram. Can anyone explain what M-RAM is, which devices have it, and any relevant documentation I should explore?

Hi,

I couldn't find much information either. All I can gather is that M-RAM is a type of memory block and probably is only available in legacy devices listed in the RAM Megafunctions User Guide.

May I know why are you interested in the M-RAM? Which device are you using?

My device does not contain M-RAM, so I'm not immediately concerned. But it would still be nice to know which devices have M-RAM, and some documentation on what it is.

Hello,

I can see that Stratix II has it: https://www.intel.com/programmable/technical-pdfs/654392.pdf

As mentioned earlier, M-RAM is a type of memory block. It is a large type of memory block: https://www.intel.com/content/www/us/en/programmable/quartushelp/18.0/index.htm#reference/glossary/def_mega_ram.htm

Another large memory block is M144K, I think the M-RAM was replaced by M144K based on internal database:
