Working Principles

The IS49NLC18320A-33WBL utilizes flash memory technology to store data. It employs a floating gate transistor structure that allows for non-volatile storage. The memory cells can be electrically programmed and erased using the SPI interface. When data is written, charges are trapped in the floating gate, altering the threshold voltage of the transistor. This change in threshold voltage determines the stored data.
