ABSTRACT:
A method for reading a memory array is disclosed. The method includes turning on the column of select gates; preprogramming a first right floating gate to a high threshold and a first left floating gate coupled to a same first word line as the first right floating gate to a low threshold; charging a voltage of the right data line to a first predetermined value; charging a voltage of the first word line to a second predetermined value which is between the high threshold of the first right floating gate and the low threshold of the first left floating gate; charging a voltage of a second word line coupled to a second right floating gate to a third predetermined value; and comparing a current of the left data line with a fourth predetermined value.
