Working Principles

The GD25S512MDYIGR is based on NAND flash memory technology. It stores data in a series of memory cells organized in a grid-like structure. Each cell can store multiple bits of information by varying the electrical charge applied to it.

To read data, the chip activates the appropriate memory cells and measures the resulting electrical current. To write data, the chip applies specific voltage levels to the selected cells, altering their charge state. Erasing data involves resetting the charge levels of entire blocks of cells.
