Yep, it isn't a new idea. The premise of Von Neumann machines is that you work around the cpu/data bottleneck with increasingly faster (and larger) caches. You have a tiny bit of ludicrously fast on chip memory (registers), a few megs of successively larger and slower L1/L2/L3 cache, a few gigs of kind of slow memory, and hundreds of gigs of unbelievably slow hard disk. This would just split the unbelievably slow disk into two separate layers - kind of slow SSD and really slow disk.
