A row decoder for a non-volatile memory device includes an input and pre-decoding module that receives address signals and generates pre-decoded address signals. A decoding module receives the pre-decoded address signals for generation on an output of decoded address signals. A driving module generates biasing signals for biasing wordlines of a memory array. The decoding module envisages a plurality of decoding stages, each of which carries out an operation of an OR logic combination between a first and a second predecoded address signal to be combined. The decoding module includes at least one first pass transistor for selectively transferring onto the output the one between the first and second predecoded address signals to be combined in a first operating condition. The decoding module includes at least one first pull-up transistor to selectively bring the output to a high state in at least one second operating condition.
