- xnorswap 3y agoOf course, but it's still a huge order of magnitude difference to get to trillions.

- MayeulC 3y agoYou don't need to refresh non-DRAM memories though. I agree that some regions risk being R/W more than others, so memory controllers should indeed perform some kind of wear levelling, but otherwise I find it hard to imagine trillions of overwrites across GBs (or TBs) of data. 1e6 cycles is definitely doable, and on the low side, even for flash devices. 1e9 is pretty good for general-purpose memories, and few applications require 1e12. Not even SRAM or DRAM have unlimited endurance, due to physical wear. It's hard to find a source on this, but I would probably hand wave it at around 1e15 cycles for DRAM? This would be 30 years of operation for one access every microsecond.
