Abstract

A non-volatile memory device is proposed. The non-volatile memory device includes a plurality of memory cells each one having a programmable threshold voltage, and means for reading a set of selected memory cells with respect to a plurality of reference voltages, for each selected memory cell the means for reading including means for charging a reading node associated with the selected memory cell with a charging voltage, means for biasing the selected memory cell with a biasing voltage, means for connecting the charged reading node with the biased selected memory cell, and means for sensing a voltage at the reading node after a predefined delay from the connection, for at least a first one of the reference voltages the biasing voltage being a first biasing voltage equal to the first reference voltage and the delay being a common first delay, wherein for at least a second one of the reference voltages the biasing voltage is a second biasing voltage different from the second reference voltage, and the delay is a second delay different from the first delay.
