DUAL IN-LINE MEMORY MODULE MAP-OUT IN AN INFORMATION HANDLING SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 17869844 titled 'DUAL IN-LINE MEMORY MODULE MAP-OUT IN AN INFORMATION HANDLING SYSTEM

Simplified Explanation

The abstract describes an information handling system that includes multiple memory modules and a basic input/output system (BIOS). The BIOS performs memory reference code training to identify a faulty memory module and stores information about it. The system is then rebooted, and the BIOS retrieves the information about the faulty module and disables the corresponding slot. The BIOS then performs a second memory reference code training to adjust the memory system based on the disabled slot.

• The information handling system has multiple memory modules (DIMMs) and a BIOS.
• The BIOS performs memory reference code training to identify a faulty DIMM.
• The BIOS stores information about the faulty DIMM and reboots the system.
• During the reboot, the BIOS retrieves the information about the faulty DIMM.
• The BIOS disables the slot associated with the faulty DIMM.
• The BIOS performs a second memory reference code training to adjust the memory system based on the disabled slot.

Potential Applications:

• Computer systems with multiple memory modules can benefit from this technology to identify and manage faulty modules.
• This technology can be used in servers, workstations, and other information handling systems that require reliable memory performance.

Problems Solved:

• This technology solves the problem of identifying and managing faulty memory modules in an information handling system.
• It ensures that the system operates with the closest possible DIMM population by disabling the faulty slot.

Benefits:

• Improved system reliability by identifying and disabling faulty memory modules.
• Efficient memory management by adjusting the memory system based on the disabled slot.
• Reduced downtime and maintenance costs by quickly identifying and managing faulty memory modules.

Original Abstract Submitted

An information handling system includes multiple dual in-line memory modules (DIMMs) and a basic input/output system (BIOS). The DIMMs form a memory system of the information handling system. The BIOS begins a system boot of the information handling system, and performs a first memory reference code training. Based on the first memory reference code training, the BIOS discovers a bad DIMM of the DIMMs, and stores information associated with the bad DIMM. The BIOS reboots the information handling system. During the reboot, the BIOS retrieves the information associated with the bad DIMM. The BIOS disables a slot associated with the bad DIMM. In response to the slot being disabled, the BIOS performs a second memory reference code training. Based on the second memory reference code training, the BIOS downgrades the memory system to a closest possible DIMM population.
