Working Principles

The N25Q256A13EF840F is based on the NOR flash memory technology. It utilizes a grid of memory cells, where each cell stores one bit of information. The data is stored by trapping electric charge within the floating gate of each cell. This trapped charge determines whether the cell represents a "0" or a "1". The SPI interface allows for easy communication with the chip, enabling read, write, and erase operations.
