So basically you just make a couple memory reads a few hundred thousands times and this will alter some near cell? why manufacturers didn't test this? it looks like a pretty obvious thing to test while working at these scales.
- mud_dauber 12y agob/c the applications that care the most about these types of errors (big iron networking, and mil/aero) implement software error correction in the processor. It's not worth spending the extra money in final test when commodity DRAM is, well, a commodity.
- johnsmith108959 12y agoYes, ECC memory, although it's mostly implemented by the chipset and DRAM modules, with only a small part of it being in the processor.
- mud_dauber 12y agoThanks for the clarification John.
- userbinator 12y agocommodity DRAM is, well, a commodity. You're essentially saying that producing DRAM that doesn't work like memory should, regardless of access pattern, is excusable because it's "commodity"?
