Working Principles
AT49F001T-55PC utilizes flash EEPROM technology to store digital information. It consists of a grid of memory cells, each capable of holding a binary value (0 or 1). The state of these cells is determined by the presence or absence of an electrical charge. During a write operation, the memory cells are programmed by applying a high voltage to specific locations, altering their charge state. Reading data involves detecting the charge levels in the memory cells and interpreting them as binary values.
