Working Principles

The W25Q128JVBIQ TR utilizes the Serial Peripheral Interface (SPI) for communication with the host device. It stores data in a grid of memory cells, each capable of holding one bit of information. The memory cells are organized into sectors and blocks, allowing for efficient read and write operations.

When data needs to be stored or retrieved, the host device sends commands and addresses to the flash memory via the SPI interface. The memory controller inside the flash memory manages the data transfer between the host device and the memory cells.
