A device employs a method for determining the data bus width of a non-volatile memory, such as NAND flash memory. The method performs at least two read operations on the non-volatile memory so as to test the changing of selected data bits. The method may be performed such that weak pull down and pull up operations are performed to test the data outputs of the non-volatile memory.

L'invention concerne un dispositif qui utilise un procédé permettant de déterminer la largeur d'un bus de données d'une mémoire non volatile, telle qu'une mémoire flash NAND. Ce procédé réalise au moins deux opérations de lecture sur la mémoire non volatile de façon à tester le changement de bits d'information sélectionnés. Ce procédé peut être appliqué de façon que des opérations de faibles rappel vers le bas et rappel vers le haut et soient réalisées afin de tester les sorties de données de la mémoire non volatile.
