1. A method of handling memory access requests in a digital memory system, said method comprising: receiving a first memory access request, said first memory access request identifying a first virtualized memory address in a virtualized memory address space; using said virtualized memory address as an index into a memory mapping table to obtain a first memory bank identifier that identifies a memory bank in a physical memory system currently storing data associated with said first virtualized memory address, said a physical memory system having a physical address space larger than said virtualized memory address space handling said first memory access request with a first physical memory address comprising said memory bank identifier and a subset of said first virtualized memory address.
