Memory bit flip rate
Web20 mei 2024 · In practice many bit-flips occur in unused memory, or have no practical effect, e.g., a bit flip only affects (x < 1000) if it changes it to a value less/greater than … A designer can attempt to minimize the rate of soft errors by judicious device design, choosing the right semiconductor, package and substrate materials, and the right device geometry. Often, however, this is limited by the need to reduce device size and voltage, to increase operating speed and to reduce power dissipation. The susceptibility of devices to upsets is described in the industry using the JEDEC JESD-89 standard.

Webmemory capacities at lower costs which in turn results in a continuous increase in densities through process scaling, 3D stacking, and storage of more bits per memory cell (MLC --> TLC --> QLC) a.k.a. logical scaling. This trend causes fundamentally “noisier” media. Ensuring data integrity and reliable storage over such media requires
Error correction codes protect against undetected data corruption and are used in computers where such corruption is unacceptable, examples being scientific and financial computing applications, or in database and file servers. ECC can also reduce the number of crashes in multi-user server applications and maximum-availability systems.
