Abstract
A method for changing computer system memory density. It is determined whether a memory unit is scalable to provide a first memory density and a second memory density. Information is received authorizing a change in the memory density. The firmware is updated to indicate the change in memory density.
Claims22
A method for changing computer system memory density, said method comprising:
- determining whether an installed and addressable memory module is scalable to provide a first memory density and a second memory density without requiring the physical installation of an additional memory module into said computer system, wherein said first memory density and said second memory density provide different amounts of addressable space of said memory module, wherein said memory module is a volatile memory module;
- receiving information authorizing a change in said memory density;
- and
- updating firmware to indicate said change in said memory density such that a memory density of said addressable space is controlled by said firmware.
A computer system comprising:
- a bus;
- a computer-readable memory coupled to said bus;
- a processor coupled to said bus;
- and
- an installed and addressable memory module coupled to said bus, said memory module scalable to provide a plurality of memory densities without requiring the physical installation of an additional memory module into said computer system, wherein said plurality of memory densities provide different amounts of addressable space of said memory module, wherein said memory module is a volatile memory module.
A computer-readable medium having computer-readable program code embodied therein for causing a computer system to perform a method for changing computer system memory density, said method comprising:
- programming a memory density of an installed and addressable memory module to a first memory density, wherein said memory module is a volatile memory module;
- receiving authorization to change said memory density from said first memory density to a second memory density, wherein said first memory density and said second memory density provide different amounts of addressable space of said memory module without requiring the physical installation of an additional memory module into said computer system;
- and
- programming said memory density to said second memory density.
