Single Event Upset
A concept in the field of aerospace electronics referring to the phenomenon in which high-energy cosmic rays or solar protons strike sensitive nodes of a chip, causing a non-destructive flip in the state of a memory cell or logic gate, potentially leading to instruction errors or deviations in computation results.
Timeline (last 90 days)
Cosmic rays can cause single-event upsets, and commercial GPUs cannot be used directly in the space environment, requiring radiation-hardened designs or redundant verification mechanisms.
A single-event upset refers to the phenomenon in which, when high-energy cosmic rays or solar protons strike sensitive nodes of a chip, the state of a memory cell or logic gate undergoes a non-destructive flip; it does not burn out the hardware, but it may cause a register bit to change from 0 to 1, leading to instruction errors or computational deviations.
In the orbital radiation environment, a satellite may encounter dozens of single-event upsets per day.
High-energy particles in orbital radiation can cause single-event upsets (SEUs), randomly flipping bit values in memory cells and triggering computational errors or system crashes.
A single-event upset (SEU) refers to the instantaneous change of a memory cell's logic state caused by a high-energy particle passing through a semiconductor device, flipping a data bit from 0 to 1 or from 1 to 0.
