A method for reading memory cells is described. The method may include applying a first read voltage to a plurality of memory cells, detecting first threshold voltages exhibited by the plurality of memory cells in response to application of the first read voltage, associating a first logic state to one or more cells of the plurality of memory cells, applying a second read voltage to the plurality of memory cells, where the second read voltage has the same polarity of the first read voltage and a higher magnitude than an expected highest threshold voltage of memory cells in the first logic state, and detecting second threshold voltages exhibited by the plurality of memory cells in response to application of the second read voltage, among other aspects. A related circuit, a related memory device and a related system are also disclosed.
