Working Principles

The S29WS256N0SBFW012 is based on NOR Flash memory technology. It utilizes a grid of memory cells that can store binary data as electrical charges. These charges are retained even when power is removed, making it a non-volatile memory solution. The memory cells are organized into sectors, which can be individually erased or programmed.

To read data from the memory, specific addresses are provided to select the desired memory cell. The stored charge is then sensed and converted back into digital data. Writing data involves applying appropriate voltages to the memory cells, modifying the stored charges accordingly.
