Working Principles

The W29GL256SH9T TR operates based on the principles of NOR flash memory technology. It utilizes a grid of memory cells, where each cell stores a binary value (0 or 1) by trapping or releasing electric charge. The stored information remains intact even when power is removed. To read or write data, specific voltage levels are applied to the appropriate pins, enabling the transfer of data between the memory cells and the external device.
