Working Principles

The W29GL032CH7B flash memory utilizes floating-gate transistors to store digital information. It employs a technique called "NAND flash memory" where data is stored in memory cells organized in a grid-like structure. Each cell can hold multiple bits of information, allowing for higher storage density. The memory cells are programmed by applying electrical charges to the floating gates, altering their threshold voltages. This change in threshold voltage determines whether a cell represents a logical 0 or 1.
