Filed: 1996-11-04
Abstract: The invention relates to a method and device for automatic determination of the required high voltage for programming/erasing an EEPROM. The present method renders it possible to determine individually the high voltage (Vpp) required to erase or program for each electrically erasable and programmable fixed-value semi-conductor memory (SP), and to store it in the memory (SP) itself in a region A provided therein. This determined high voltage can be retrieved from said region for any further erasing or programming. From a first value of the high voltage for programming or erasing the memory and a first value of a reading voltage for checking of programming or erasing, the most advantageous high voltage is determined by successively modifying either the high voltage or the reading voltage.
