bit flip

This term is primarily used in computer science and electrical engineering to describe a hardware-level error. It carries a connotation of unpredictability and fragility, as these events are often caused by external environmental factors like cosmic radiation or electromagnetic interference rather than software bugs.

In technical discourse, it is frequently discussed alongside "ECC" (Error Correction Code) memory, which is designed specifically to detect and fix these occurrences. Because it refers to a discrete event of a single bit changing state, it is treated as a countable occurrence in technical reports.
