ECC can also reduce the number of crashes in multi-user server applications and maximum-availability systems. Electrical or magnetic interference inside a computer system can cause a single bit of dynamic ... circuit into the CPU, even before the shift toward CPU-integrated memory controllers, which are … See more Error correction code memory (ECC memory) is a type of computer data storage that uses an error correction code (ECC) to detect and correct n-bit data corruption which occurs in memory. ECC memory is used in … See more Work published between 2007 and 2009 showed widely varying error rates with over 7 orders of magnitude difference, ranging from 10 error/bit·h (roughly one bit error per hour per … See more Seymour Cray famously said "parity is for farmers" when asked why he left this out of the CDC 6600. Later, he included parity in the CDC 7600, which caused pundits to remark that "apparently a lot of farmers buy computers".
