MECHANISM TO OVERRIDE STANDBY POWER IN LARGE MEMORY CONFIGURATION OF WORKSTATIONS TO ELIMINATE THE NEED TO INCREASE POWER OF STANDBY POWER RAIL - A simplified explanation of the abstract

This abstract first appeared for US patent application 18077131 titled 'MECHANISM TO OVERRIDE STANDBY POWER IN LARGE MEMORY CONFIGURATION OF WORKSTATIONS TO ELIMINATE THE NEED TO INCREASE POWER OF STANDBY POWER RAIL

Simplified Explanation

The circuit described in the patent application allows for the re-use of existing power supply units in computing devices to support large memory configurations while in a sleep state to prevent data loss.

• The processor checks if the power requirement of memory modules exceeds the available power of the auxiliary power rail.
• If so, the processor sends an override signal to keep the power supply on in the sleep state.
• Switches disconnect the main power rails from components that can be turned off in the sleep state.
• A select circuit chooses one of the main rails to power the memory modules.

Key Features and Innovation

• Re-uses existing power supply units for large memory configurations in a sleep state.
• Processor determines power requirements of memory modules and controls power supply accordingly.
• Override signal keeps power supply on in sleep state if needed.
• Switches disconnect unnecessary components to save power.
• Select circuit chooses main rail to power memory modules.

Original Abstract Submitted

Embodiments herein relate to a circuit which allows the re-use of an existing power supply units having main power rails and an auxiliary power rail, while supporting large memory configurations in a sleep state to avoid data loss. A processor determines whether a power requirement of memory modules in a computing device exceeds an available power of the auxiliary power rail. If this is the case, the processor asserts an override signal which is used by a logic circuit to force the power supply to remain on in the sleep state. A set of switches disconnect the main rails from other components which can be turned off in the sleep state. A select circuit selects one of the main rails to power the memory modules.
