Working Principles

The M29W320DB80ZA3E flash memory utilizes a floating gate transistor structure to store digital data. It employs a combination of electric fields and charge trapping to retain information even when the power is turned off. The memory cells are organized into sectors, allowing for efficient erasure and programming operations.

During read operations, the addressed memory cell's stored charge is sensed, and the corresponding data is outputted. Write operations involve applying higher voltages to the memory cells, modifying the charge trapped in the floating gate to represent new data.
