Working Principles

The M29DW256G7ANF6E flash memory chip utilizes a floating-gate transistor structure to store and retrieve data. It employs a combination of electrical charges to represent binary information. The memory cells are organized into sectors and blocks, allowing for efficient erasure and programming operations.

During write operations, the memory cells are programmed by injecting electrons into the floating gate, altering its electrical characteristics. Reading data involves sensing the charge state of the memory cells. Erasing is performed at the block level, where all cells within a block are simultaneously reset to an erased state.
