Working Principles

The W29GL064CH7B operates based on the principles of NOR flash memory. It utilizes a grid of memory cells, where each cell stores a bit of data. The memory cells are organized into sectors and blocks, allowing for efficient read and write operations. When data is written, the memory cells are programmed by applying electrical charges. During read operations, the stored charges are detected and converted back into digital data.
