< 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.
