Working Principles

The M29W400DT45ZE6E flash memory chip utilizes NOR flash technology. It stores data using a grid of memory cells, each capable of holding one or more bits of information. The memory cells are organized into sectors, which can be individually erased or written. When reading data, the chip activates the appropriate memory cells and retrieves the stored information. During write operations, the chip applies high voltages to modify the state of the memory cells, allowing new data to be stored.
