Working Principles

The M28W320FCT70N6F TR utilizes NOR flash memory technology. It stores data in a grid of memory cells, where each cell represents a bit of information. The memory cells are organized into sectors and blocks for efficient read and write operations. When data is written, the memory cells are programmed with electrical charges to represent the desired information. During read operations, the charges in the memory cells are detected and converted back into digital data.
