Bit flip radiation

WebRadiation damage to on-board electronics may be separated into two categories: total ionizing dose and single event effects. Total ionizing dose (TID) is a cumulative long-term degradation of the device when exposed to ionizing radiation. ... Soft errors are nondestructive to the device and may appear as a bit flip in a memory cell or latch, or ... WebMay 29, 2015 · In case anyone is wondering, the reason for the triple redundancy is that solar radiation can cause bits to flip e.g. from 0 to 1, which can completely throw out calculations. So, there have to be a number of cores in agreement so that if one of the cores has been affected by a bit flip, it can be detected. – Chris Halcrow Feb 13, 2024 at 20:53 4
