Working Principles

The MX29F040CQC-90G utilizes NOR flash memory technology. It stores data in a grid of memory cells, where each cell represents a bit of information. These cells are organized into pages and blocks, allowing for efficient read and write operations. When data is written, the memory cells are electrically programmed to store the desired information. During read operations, the stored data is retrieved by sensing the electrical state of the memory cells.
