Working Principles
The AT49LV1024-70VC utilizes flash EEPROM technology to store and retrieve digital information. It consists of a grid of memory cells, with each cell capable of storing one bit of data. The data is stored by trapping electric charges within the floating gate of each memory cell. These trapped charges represent the binary states of 0 or 1.
To write data, a high voltage is applied to the control gate, allowing electrons to tunnel through the insulating layer and into the floating gate. This process alters the charge distribution within the floating gate, effectively changing the stored data.
Reading data involves applying appropriate voltages to the control gate and accessing the resulting current flow through the memory cell. The magnitude of the current indicates the stored data state, which can be interpreted as either a logic 0 or logic 1.
