In computer technology, dynamic random access memory ( DRAM ) " soft errors " were linked to alpha particles in 1978 in Intel's DRAM chips.

BPSG has been implicated in increasing a device's susceptibility to soft errors since the boron-10 isotope is good at capturing thermal neutrons from cosmic radiation.
33.
The design of error detection and correction circuits is helped by the fact that soft errors usually are localised to a very small area of a chip.
34.
These rare, so-called soft errors are created by cosmic rays and naturally occurring background radiation from trace elements like radium and thorium found in materials like lead.
35.
For instance, many failures per million circuits due to soft errors can be expected in the field if the system does not have adequate soft error protection.

37.
So, an error correcting code needs only to cope with a single bit in error in each correction word in order to cope with all likely soft errors.
38.
Dr Emer has also contributed to simultaneous multithreading ( SMT ), memory dependence prediction via store sets, soft error analysis, and led the development of the Asim simulator.
39.
Hard errors arise when a physical area on your disk becomes unreliable; soft errors occur when your operating system or file system loses track of parts of a file.
40.
Chip-level soft errors occur when particles hit the chip, e . g ., when the radioactive atoms in the chip's material decay and release alpha particles into the chip.
