Working Principles

The N25Q128A13EF840E operates based on the principles of flash memory technology. It utilizes a grid of memory cells, each capable of storing electrical charges to represent binary data. The memory cells are organized into sectors and blocks, allowing for efficient read, write, and erase operations.

During a read operation, the device receives commands and address information from the host device. The requested data is then retrieved from the appropriate memory cells and transmitted back to the host.

Write operations involve sending commands, address information, and data to be stored. The device programs the memory cells by applying voltage pulses that trap charges, representing the desired data.

Erase operations clear data by removing trapped charges from memory cells. This can be done at the sector, block, or chip level, depending on the desired granularity.
