Abstract
A method of controller optimization utilizing over-sampling read (OSR) in a memory device includes performing a first internal read at a predetermined threshold level and transferring the first internal read measurement to the controller, performing a second internal read in a range that is between the predetermined threshold level plus a first predetermined value and the predetermined threshold level minus a second predetermined value, and determining whether a cell level falls in the range and transferring the second internal read measurement to the controller.
