Memory: Think of as single one-dimensional array where each cell ! Stores a byte size value ! Is referred to by a 32 bit address e.g. value at 0x4000 is 0x0a ! Data is stored in memory as: variables, arrays, structures ! But ARM arithmetic instructions only operate on registers, never directly on memory.
