Method and system for managing a writing cycle of a data in a EEPROM memory cell

摘要

An operation for writing at least one datum in at least one memory cell of the electrically erasable and programmable read-only memory type comprises at least one step of erasing or of programming of the cell by a corresponding erasing or programming pulse. The correct or incorrect conducting of the writing operation is checked by an analysis of the form of the erasing or programming pulse during the corresponding erasing or programming step. The result of this analysis is representative of the writing operation being conducted correctly or incorrectly.

1. A method for operating an electrically erasable and programmable read-only type memory device, the method comprising:
performing a write operation by erasing or programming to a memory cell using a corresponding an erasing pulse or a programming pulse; and analyzing a form of the erasing pulse or programming pulse during the corresponding erasing or programming step, a result of the analyzing being representative of whether the write operation was performed correctly or incorrectly.
