Abstract

Methods and devices are disclosed, such methods comprising applying a verify pass-through voltage to unselected select lines of the floating-gate memory array that is greater than a read pass-through voltage applied to the unselected select lines. Other methods involve utilizing a cell current for reading a value from one or more memory cells in program-verify operations that is lower than a cell current for reading value from one or more memory cells in read operations.
