Abstract: The row decoder includes a predecoding stage (203) supplied with row addresses and generating predecoding signals; and a final decoding stage (204), which, on the basis of the predecoding signals, drives the individual rows in the array. The predecoding stage (203) includes a number of predecoding circuits (15) presenting two parallel signal paths: a low-voltage path (30) used in read mode, and a high-voltage path (31) used in programming mode. A CMOS switch (32) separates the two paths, is driven by high voltage via a voltage shifter (45) in programming mode, and, being formed at predecoding level, involves no integration problems.
