Abstract
A memory device is a provided that includes memory cells situated at the intersection of lines and columns, and a dummy path including a first dummy column having two bit lines to which there are connected dummy memory cells, and a circuit adapted to select at least one of the dummy memory cells to discharge one of the dummy bit lines. The dummy path also includes at least one second dummy column adapted to generate a dummy leakage current (representing a leakage current of a column of the memory device selected in read mode), and a circuit adapted to copy the dummy leakage current to the one dummy bit line, so that the discharge of the one dummy bit line also depends on the dummy leakage current.
