The memory array of the device is organized into uniform 4 Kbyte sectors or 32/64/256 Kbyte uniform blocks (a block consists of eight/sixteen adjacent sectors respectively). Before a byte is reprogrammed, the sector or block that contains the byte must be erased (erasing sets bits to “1”). In order to erase the device, there are three erase instructions available: Sector Erase (SER), Block Erase (BER), and Chip Erase (CER). A sector erase operation allows any individual sector to be erased without affecting the data in other sectors. A block erase operation erases any individual block. A chip erase operation erases the whole memory array of a device. A sector erase, block erase, or chip erase operation can be executed prior to any programming operation. |
