ELECTRONIC SYSTEM INCLUDING A DEVICE FOR ESTIMATING AN ELECTRONIC MEMORY FAULT SUBJECT TO HIGH ALTITUDE FLIGHT CONDITIONS

摘要

The invention relates to an electronic system (1) for aeronautical applications comprising at least one electronic memory (2) comprising a first plurality (T) of words and an error detection system (4) of said words. The electronic system according to the invention comprises an error counting device comprising: a register (6) comprising a second plurality (NBR) of bits, a one-bit address being associated with at least one word; means for indexing the bit associated with said word when the error detection system signals an alteration of said word, the indexing of said bit being unique in a given period of time, regardless of the number of times the alteration of said word is detected by the error detection system within that given period of time; Means for resetting (5) the register at the end of the given period of time.
