Working Principles

The M29W320DT90N6 is based on flash memory technology, which uses floating-gate transistors to store and retrieve data. It operates by applying electrical voltage to specific memory cells, allowing electrons to tunnel through a thin oxide layer onto the floating gate. This process alters the transistor's threshold voltage, representing a binary state (0 or 1). Data can be read by sensing the threshold voltage of each memory cell.
