Abstract
The invention concerns a memory cell insensitive to disturbances. The memory cell, that contains information in the form of two complementary logical levels (X, C(X)), each logical level being stored in a node of the cell (N1, N2), is characterized in that it comprises means of storing the same logical level in two different nodes (N1, N2, N3, N4), the said means being able to restore any logical level to its initial state preceding a modification made on it due to a disturbance, as a result of holding the value of one of the two logical levels complementary to the logical level that was modified.
