Working Principles

The JS28F640J3D75E flash memory chip uses a floating gate transistor technology to store data. It consists of numerous memory cells, each capable of storing a single bit of information. The data is stored by trapping or releasing electric charge in the floating gate of the transistor. This trapped charge represents either a "0" or a "1" bit.

During read operations, the stored charge is measured to determine the value of the bit. Write and erase operations involve applying specific voltage levels to the memory cells to modify the charge in the floating gate.

Detailed Application Field Plans

The JS28F640J3D75E flash memory chip finds applications in various electronic devices, including:

  1. Mobile phones
  2. Digital cameras
  3. Portable media players
