System and methods for memory expansion

A system comprising:

• retrieving means for retrieving first initialization data from a physical dual inline memory module (DIMM);
• converting means for converting the first initialization data to second initialization data of a logical DIMM mapped to the physical DIMM, the converting means including a computer-implemented linear function that multiplies a first initialization value included in the first initialization data by a factor to determine a second initialization value included in the second initialization data, the first initialization value corresponding to a first memory capacity of the physical DIMM and the second initialization value corresponding to a second memory capacity of the logical DIMM;
• and
• programming means for programming a memory controller based on the second initialization data corresponding to the logical DIMM to control memory access to the physical DIMM.

A system comprising:

• a basic input output system (BIOS) module communicatively coupled with a physical dual inline memory module (DIMM) and a memory controller, the BIOS module configured to:
• retrieve first initialization data from the physical DIMM;
• convert the first initialization data to second initialization data of a logical DIMM mapped to the physical DIMM, the converting of the first initialization data to the second initialization data being based on a linear function that multiplies a first initialization value included in the first initialization data by a factor to determine a second initialization value included in the second initialization data, the first initialization value corresponding to a first memory capacity of the physical DIMM and the second initialization value corresponding to a second memory capacity of the logical DIMM;
• and
• program the memory controller based on the second initialization data corresponding to the logical DIMM to control memory access to the physical DIMM.

A non-transitory machine-readable medium having instructions that, when executed by a processing system, cause the processing system to:

• retrieve first initialization data from a physical dual inline memory module (DIMM);
• convert the first initialization data to second initialization data of a logical DIMM mapped to the physical DIMM, the converting of the first initialization data to the second initialization data being based on a linear function that multiplies a first initialization value included in the first initialization data by a factor to determine a second initialization value included in the second initialization data, the first initialization value corresponding to a first memory capacity of the physical DIMM and the second initialization value corresponding to a second memory capacity of the logical DIMM;
• and
• program a memory controller based on the second initialization data corresponding to the logical D1MM to control memory access to the physical DIMM.
