Working Principles

The M29W256GL70N6E chip utilizes flash memory technology, which is a type of non-volatile memory. It stores data using electrically erasable and programmable memory cells. The chip can be erased and programmed at the sector level or as a whole. When data is written, an electrical charge is applied to the memory cells, altering their state. This allows for reliable storage and retrieval of digital information.
