When the target Flash is erased, the Flash reads as all 1s. This state is called 'blank.' The erase function must be executed before programming. The user cannot skip erase on sectors that read as 'blank' because these sectors can require additional erasing due to marginally erased bits columns. The FSM provides an Erase Sector command to erase the target sector. The erase function erases the data and the ECC together.
