摘要: This invention discloses a method of erasing a flash memory, in which the method comprises: (A) erasing all cells of a selected sector; (B) verifying in cells whether the cells are erased; (C) saving an address corresponding to a non-erased cell and re-erasing the cells when the non-erased cell is detected by the step (B); (D) verifying in cells, from the saved address to the final address whether the cells are erased; and (E) executing a slight-program for recovering over-erased cells so that the cells of the sector are normally erased.

摘要: (The present invention discloses) a method of pre-programming a flash memory cell. According to the present invention, it makes it possible to execute a continuous programming by performing a pre-programming step of internal algorithms with a bulk program verification step not with a byte or word pre-programming step when an erasure operation of a flash memory cell using a stack gate cell is performed.
