The write operation causes data to be written to the flash device. The simplest writing scheme allows writing a word of data to any address in a block. Many flash devices provide more advanced writing schemes, such as using a small buffer, and use of these can significantly speed up write operations. When developing a new flash algorithm it is recommended that you first implement the simplest writing scheme, and when that is working correctly, then consider whether attaining a faster writing speed is important enough to require a more complex implementation.
