    摘要: Described herein is a method for biasing an EEPROM array formed by memory cells arranged in rows and columns, each operatively coupled to a first switch and to a second switch and having a first current-conduction terminal selectively connectable to a bitline through the first switch and a control terminal selectively connectable to a gate-control line through the second switch, wherein associated to each row are a first wordline and a second wordline, connected to the control terminals of the first switches and, respectively, of the second switches operatively coupled to the memory cells of the same row. The method envisages selecting at least one memory cell for a given memory operation, biasing the first wordline and the second wordline of the row associated thereto, and in particular biasing the first and second wordlines with voltages different from one another and having values that are higher than an internal supply voltage and are a function of the given memory operation.
