It is just a block of memory with a base start address and a length.
Can be read by 
    LDR[B] {baseregister,offfsetregister} 
in some form or other, and written using STR[B].
Using LDM/STM for multiple words at a time if it suits your use will
probably be faster.

Lots of opportunity to read and even write to the wrong place!
Can be nasty.
