Working Principles

The N25Q064A11ESF40G is based on flash memory technology. It utilizes a grid of memory cells, where each cell can store multiple bits of data. The data is stored by trapping electric charges within the floating gate of each memory cell. These charges represent the binary values of the stored data.

During read operations, the charges in the memory cells are measured to determine the stored data. Write operations involve applying voltage pulses to the memory cells to either trap or release charges, modifying the stored data.

The Serial Peripheral Interface (SPI) allows for communication between the N25Q064A11ESF40G and external devices, enabling data transfer and control signals.
