The really exciting part here, to me, is the idea of fabricating large amounts of nonvolatile memory on top of a CPU. Modern processors already spend a huge amount of their time waiting on memory, and a great amount of power trying to hide that memory latency. If these guys can lower memory latency dramatically -- and it looks like they can -- computers would get a lot faster.
- TheEzEzz 15y agoThis would be a huge boon for scientific computing. The data is often huge, but all of it must be constantly pushed through the CPU every iteration.
- montecarl 15y agoAs the number of cores per socket is steadily increasing it is becoming more difficult to keep all of the cores on a single computer operating efficiently. A higher clock rate per core, or more cores per socket, is not very useful if they are all waiting on memory.
- rbanffy 15y agoUnless we are considering coupling lots of memory to the cores themselves, bypassing slow external buses.
- pjscott 15y agoNow imagine a large amount of memory connected to the cores through tiny metal wires on the chip itself. Now imagine that it's split into a bunch of small independent memories with enormous bandwidth, with data automatically migrating between them to cut down on wire delays. Give it a few years, and this could be reality.
