Patent ID: 7274595

Claim:
A method for erasing or programming a nonvolatile memory device for storing data comprising at least one memory cell, at least one sense amplifier for reading out the content of the at least one memory cell, and a page memory for buffer-storing data used as a basis for defining the driving of the at least one memory cell during the erasure or programming, the erasure or programming of a memory cell comprising the following steps of: performing an erasure or programming operation in a manner dependent on the data stored in the page memory, reading out the content of the erased or programmed memory cells, modifying the content of the page memory in a manner dependent on the data read out, and performing a further erasure or programming operation in a manner dependent on the modified data, and the data read out from the erased or programmed memory cell being fed to the page memory, and the content of the page memory being modified in a manner solely dependent on these data and control signals controlling the temporal sequence.
