Working Principles

The M29W400DB70N6T TR is based on NOR flash memory technology. It utilizes a grid of memory cells, where each cell stores a bit of information as an electrical charge. The memory cells are organized in a matrix, with rows and columns forming the addressable locations.

During read operations, the addressed memory cell is selected, and its stored charge is sensed to determine the data value. Write operations involve applying appropriate voltages to program or erase the memory cells, altering their charge state to store new data.
