Working Principles

The AT49BV1604AT-90TI utilizes the principles of flash memory technology. It consists of a grid of memory cells, each capable of storing a single bit of information. These cells are organized into sectors, allowing for efficient management of data storage and retrieval.

During a write operation, the desired data is programmed into the memory cells using an electrical charge. The stored data can be read by applying appropriate voltage levels to the memory cells. The non-volatile nature of flash memory ensures that the stored data remains intact even when power is removed.
