Data Protection

The device has hardware features to protect against Program and Erase operations.

It features a Write Protect, WP, pin, which can be used to protect the device against program

and erase operations. It is recommended to keep WP at VIL during power-up and power-

down.

Embedded ECC accelerator

The NAND04GA3C2A and NAND04GW3C2A devices include a powerful embedded Error

Correction Code (ECC) accelerator. This feature ensures high memory reliability and fast

data throughput while simplifying the design of the memory application.

If the embedded ECC accelerator cannot be used, it is strongly recommended to use an

external hardware accelerator to maintain the same data throughput. If this proves to be

impossible, a software ECC can be implemented. However, this solution will result in lower

performance compared to the hardware ECC solution.

The ECC operation and command set are described in a dedicated application note. Please

contact the nearest STMicroelectronics sales office for

further details.
