Working Principles

The AT49F001T-12VI utilizes flash EEPROM technology to store and retrieve digital information. It consists of a grid of memory cells, each capable of holding one bit of data. These cells are organized into rows and columns, forming an addressable array.

To write data, the device applies a high voltage to the selected memory cell, causing electrons to be trapped in a floating gate. This alters the cell's electrical characteristics, representing a binary value (0 or 1). Reading data involves sensing the voltage level of each memory cell and interpreting it as a binary value.
