Yes, ARM has this small amount of SRAM. Having a bit of memory available was such a trivial concept that I did not even think of that the much more complicated x86 processor could just lack it.

But I guess this might not be the only fundamental difference.

(I have thought to utilize the SRAM for some optimization later at system runtime because it should be incredibly fast. At least if you don't have to care about power consumption that should be possible or does the specification require to turn it off?)
