Working Principle

At its core, the AT27BV512-12TC is an extended configuration of NAND Flash memory. In essence, NAND Flash memory is divided into a number of smaller blocks of memory, called Flash Cells. Each cell contains a predefined number of bits, which are grouped together in bytes. These bytes are electrically connected to form the memory array.

The array is connected to an address bus and data bus, which allow the memory to connect to other devices. It is also connected to control logic, which is responsible for managing the cell-level operations. This includes reading and programming data, as well as refreshing and erasing cells.

The refresh and erase operations are carried out using special techniques to ensure the efficiency and reliability of the memory. During the refresh operations, data from the Flash Cells is read and compared to its stored version. If the two versions differ, the difference is corrected and the data is stored once again.

The erase process is simple. A special "erase" command is sent to the Flash Cell, which erases its contents. This operation is necessary for transferring new data, as the old data must be cleared before the new data can be stored. Once the erase process is complete, the new data can be programmed into the Flash Cells.

The AT27BV512-12TC is a type of Non-Volatile Memory (NVM), meaning it can store data permanently without a power source. It is also configured to be highly resilient and reliable, allowing it to be used in critical environments. The AT27BV512-12TC is a versatile, reliable, and highly compatible memory solution.
