Abstract
An optimal read threshold estimation method includes determining a flip difference corresponding to an optimal step size Δopt, estimating a first slope m1 at a first read point and a second slope m2 at a second read point, and obtaining an optimal read threshold (XLPopt) as the intersection of a first line with the first slope m1 and a second line with the second slope m2.
