Sure.  But from when I last read about the IRAM stuff, I'm pretty sure
it was strictly single core.  Their VIRAM1 chip had 13 MB of DRAM, 1
cpu core, and 4 "vector lanes", with no mention of SMP or any sort of
multi-chip parallelism at all.  If Venray has a good design for using
hundreds or more IRAM-like chips in a parallel machine, that sounds
like a significant step forward.  (The intended fab process and
attendant design rules might also be quite different, although I'm not
at all sure about that.)
