Abstract
A memory device includes a plurality of memory cells each one for storing a value, at least one reference cell, biasing means for biasing a set of selected memory cells and the at least one reference cell with a biasing voltage having a substantially monotone time pattern, means for detecting the reaching of a threshold value by a current of each selected memory cell and of each reference cell, and means for determining the value stored in each selected memory cell according to a temporal relation of the reaching of the threshold value by the currents of the selected memory cell and of the at least one reference cell. The biasing means includes means for applying a controlled biasing current to the selected memory cells and to the at least one reference cell.
