Good point! Do we need to qualify this with saying over 2^64 bytes? What is the mose memory you can get in a machine with current hardware and constant latency

Good point!
Do we need to qualify this with saying over 2^64 bytes? What is the mose memory you can get in a machine with current hardware and constant latency? Just goes to show how much more important the space effect is vs. the addressing effect.
No doubt if we tried to have 2^64 bytes of memory we would end up with another layer of cache or 2.
- kragen 11y agoThe most memory I've seen on a machine with current hardware and constant latency is 512 kilobytes, like in some of the Atmel ARM SAM D1 chips. Above that, you start getting into off-chip buses‚ which generally have substantially higher latency, even before you get to the extra latencies added by DRAM chips.
