Forward looking algorithm for vertical integrated cross-point array memory

Systems and methods for reading a first and second plurality of memory cells include applying a first ramping voltage with a first increment for each ramping step to read the first plurality of cells, counting, among the first plurality of cells at each ramping step, a first number of logic 1 cells, comparing the first number with a threshold at each ramping step of the first ramping voltage, determining a first voltage reached by the first ramping voltage, at the first voltage the first number becoming equal to or higher than the threshold for the first time, applying a second voltage lower than the first voltage to read the second plurality of cells, and applying a second ramping voltage ramping up from the second voltage with a second predetermined increment lower than the first predetermined increment for each ramping step to read the second plurality of cells.
