Memory organization

Memory organization

The memory is organized as:

● 2048 pages (256 bytes each)

● 524,288 bytes (8 bits each)

● 128 subsectors (32 Kbits, 4096 bytes each)

● 8 sectors (512 Kbits, 65536 bytes each)

Each page can be individually:

– programmed (bits are programmed from 1 to 0)

– erased (bits are erased from 0 to 1)

– written (bits are changed to either 0 or 1)

The device is page or sector erasable (bits are erased from 0 to 1).
