Working Principles

The 93AA46AT-I/OT utilizes an array of floating-gate transistors to store digital information. When data needs to be written, a high voltage is applied to the gate, allowing electrons to tunnel through the insulating layer and become trapped in the floating gate. This process alters the transistor's threshold voltage, representing a binary value. To read the stored data, the transistor's threshold voltage is measured, determining the stored bit value.

Detailed Application Field Plans

The 93AA46AT-I/OT can be used in various applications, including: 1. Automotive electronics: Used for storing critical vehicle data, such as mileage, settings, and diagnostic information. 2. Consumer electronics: Integrated into devices like smartwatches, remote controls, and portable audio players to store user preferences and configuration settings. 3. Industrial automation: Employed in control systems to store calibration data, equipment parameters, and operational settings. 4. Medical devices: Utilized for storing patient-specific data, device configurations, and usage history in medical equipment.
