Bit flip radiation
WebSep 16, 2024 · A single-event upset is a change of a binary state in a bit - either from a 0 to a 1, or vice versa - caused by an ionizing particle colliding with a sensitive microelectronic device. This occurs because of a discharge in the storage elements (the memory bits) after a free charge is created by ionization of the particle near the node. 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

WebModern DRAMs have much smaller feature sizes, so the deposition of a similar amount of charge could easily cause many more bits to flip. The design of error detection and …
WebInternal charge deposition causes a ”bit flip” in a memory element or change of state in a logic circuit. SEU occurs in e.g. computer memories and microprocessors. Possibly non-Destructive effects: •Corruption of the information stored in a memory element. •Usually not permanent damage; a memory element/logic state can be refreshed WebSolar Proton Events and cosmic rays are known to be associated with bit flips - Single Event Upsets, or SEUs - in computer memory. Charged particle impact in memory causes the value of the impacted bit to change, …
WebJun 21, 2024 · Single-event upset can corrupt data when a radiation-charged particle flips a data bit from a one to a zero, or vice versa, which corrupts data.
