Thats what the site says. So what IS the difference for tmpfs on these devices? You need nv-ram anyways ...

pramfs is in NV-RAM. NV-RAM is RAM with a constant power source. An example is the so called CMOS, which is the place where the BIOS stores its settings on desktop machines. That's why a desktop mainboard has a 3.3 V battery...
So while you may have 16 GB RAM you have around 1 MB (maybe less... I think it starts from 16 KB?) NV-RAM, which is still filled up by the BIOS. That's why PRAMFS targets embedded devices...
