Overview
Many commands operate on the main flash memory array. Some commands operate on address spaces
separate from the main flash array. Each separate address space uses the full 24-bit address but may only
define a small portion of the available address space.
Flash Memory Array
The main flash array is divided into erase units called sectors. The sectors are uniform 4 kbytes in size.
