Working Principles

The W29GL032CT7B flash memory utilizes NOR-based technology. It stores data in individual memory cells, which are organized into sectors. The memory cells can be electrically programmed and erased using specific voltage levels. When reading data, the memory controller sends an address to the flash memory, which retrieves the stored information from the corresponding memory cell.
