Working Principles

The AT49LV002NT-90JI utilizes flash memory technology to store and retrieve data. It consists of a grid of memory cells, where each cell can store a bit of information. These cells are organized into rows and columns, forming an addressable array.

To write data, the appropriate address is provided along with the data to be stored. The write enable (WE#) signal is activated, allowing the data to be written into the specified memory cell. Reading data involves providing the desired address and activating the output enable (OE#) signal
