Abstract

The method comprises the steps of detecting the trailing edge of an initialization signal, and generating a read bias signal and a read activation signal for the cell, when the trailing edge of the initialization signal is detected. The signals of read bias and read activation have a ramp-like leading edge and both signals are disabled when reading of the cell is completed. Thereby, phenomena of soft-writing of the cell are avoided, and risks of erroneous readings are reduced.
