A multilevel nonvolatile memory includes a supply line (28) supplying a supply voltage (VDD), a voltage boosting circuit (26) supplying a boosted voltage (Vp), higher than the supply voltage (VDD), a boosted line (30) connected to the voltage boosting circuit (26) and a reading circuit (25) including at least one comparator (35). The comparator (35) includes a first and a second input (35a, 35b), a first and a second output (45a, 45b), at least one amplification stage (40) connected to the boosted line (30), and a boosted line latch stage (41) connected to the supply line (28).
