Working Principles

The AT49LV1024-90VC utilizes flash memory technology to store data. It consists of a grid of memory cells that can be electrically programmed and erased. When data is written to the memory, charges are trapped in the floating gate of each memory cell, representing the stored information. These charges can be retained for long periods, even without power. To read the data, the charges are sensed and interpreted as binary values.
