Working Principles

AT49F002-55JI utilizes the Floating Gate MOS (FGMOS) technology to store data. It employs a grid of memory cells, where each cell consists of a floating gate transistor. The presence or absence of an electrical charge on the floating gate determines the stored data value (0 or 1). The data can be written by applying appropriate voltage levels to the control pins, and it can be read by activating the read mode.

Detailed Application Field Plans

AT49F002-55JI finds extensive use in various electronic devices, including but not limited to: - Personal computers - Laptops and notebooks - Smartphones and tablets - Digital cameras - Gaming consoles - Automotive electronics - Industrial control systems
