Abstract
The invention relates flash memory programming techniques. An object of the invention is to provide a flash memory programming technique avoiding problems of the known state of the art and in particular, saving a significant amount of time during the development and/or production phases of any equipment containing flash memory devices and also saving time during an updating or upgrading procedure of such an equipment already being in use. Accordingly, the invention proposes for programming a flash memory device to program only differences in information between data already stored in the flash memory device and new data to be stored.
Claims11
A method for flash memory programming comprising the step of programming only differences in information between data already stored in a flash memory device and new data to be stored therein.
A flash memory device comprising several erasable and programmable sectors with defined data embedded therein, characterised in that the embedded data are ordered within the sectors in dependence on the likelihood of changing the respective data.
