The present invention is directed to a method for increasing the operational lifetime of a flash memory device, wherein, the method comprises varying the operating parameters of the flash memory device over the lifetime of the flash memory device over thr lifetime of the flash memory device. The advantage of providing a method which varies the operating parameters of a flash memory device is that the operational lifetime of the flash memory device will be increased. Relatively low voltages and relatively short voltage periods may be used initially to write to, read from and erase the flash cells in the flash memory device. As time passes, the flash cells in the flash memory device will begin to degrade and it will be necessary to increase the viltage and the period of the viltage applied to the flash memory device in order to ensure that the correct write, read and/or erase commands are carried out. The invention is also directed towards a flash memory device. <Figure 1> |
