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 LargeDatabases 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.
