Very Large Memory

from The Free On-line Dictionary of Computing (8 July 2008)
Very Large Memory

   <architecture> (VLM) A {processor} and {operating system} that
   can use more than 4GB of {RAM}, which is the limit for systems
   using {32-bit} addresses.

   VLM architectures allow {application programs} and {Very Large
   Databases} with more than 4GB of data to be placed entirely in
   {physical memory}, with large performance enhancements.

   Some recent processors like the {DEC Alpha} can process 64
   bits of data at a time and use addresses wider than 32 bits.
