Working Principles

The M29W640GH70ZA6E flash memory operates based on the principles of floating-gate transistors. It uses a grid of memory cells, each consisting of a floating-gate transistor that can store electrical charge. The presence or absence of charge determines the binary state of each memory cell.

During a write operation, an electric charge is applied to the floating gate, altering its state. Reading involves applying voltage to the selected memory cell and detecting the resulting current flow, which indicates the stored data.
