address
Character code that identifies a specific location (or series of locations)
in memory
address space
A set of 2n memory locations differentiated from other such sets in
VXI/VMEbus systems by six addressing lines known as address
modifiers. n is the number of address lines required to uniquely specify
a byte location in a given space. Valid numbers for n are 16, 24, and 32.
In VME/VXI, because there are six address modifiers, there are 64
possible address spaces.
