Abstract
A nonvolatile memory device and programming method and apparatus therefore are described that include operatively coupled first and second sense amplifiers having first and second data registers or latches, a storage circuit for storing a data of the second amplifier, a pass/fail check circuit for checking the content of the second data register whether a cell of the memory device has been sufficiently programmed and a restore circuit for resetting the second data register for reprogramming the device until sufficiently programmed.
