In one or more of the disclosed embodiments, a memory device is provided that reads a target memory cell by first charging the series string of memory cells to which the target memory cell is coupled. A fixed unit of charge is removed from the charged bit line. The bit line is sensed by sense amplifiers to determine the read voltage (i.e., threshold voltage) applied to a word line coupled to the target cell in order to turn on the target cell. The threshold voltage is indicative of the analog voltage stored on the target memory cell.
