Working Principles

The AT49F002T-70JC utilizes flash memory technology to store data. It consists of a grid of memory cells, where each cell can store a bit of information. The data is stored by trapping electric charges within the floating gate of each memory cell. These trapped charges determine whether the cell represents a "0" or a "1". The stored data can be accessed and modified using specific control signals.
