Assignee: DELL PRODUCTS L.P.
Field: Computer technology (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 19:
20. An information handling system, comprising:
a central processing unit;
a Baseboard Management Controller: and
a fifth generation double data rate (DDR5) dual in-line memory module (DIMM);
a voltage regulator configured to provide a voltage rail to the DDR5 DIMM, wherein, in a first mode, the voltage rail is based upon a pulse frequency modulation, and in a second mode, the voltage rail is based upon a forced continuous conduction mode, a selection of one of the first mode and the second mode being based upon a first input to the voltage regulator;
wherein when the information handling system is in a first state, the information handling system provides a first input signal to the first input to direct the voltage regulator to operate in the first state, and when the information handling system is in a second state associated with a sleep mode of the information handling system, the information handling system provides the first input signal to the first input of the voltage regulator to direct the voltage regulator to operate in the second state;
wherein the Baseboard Management Controller is configured in the first state to provide a second input signal to a second input of the voltage regulator to enable operation of the voltage regulator, and upon detection of a transition from the first state to the second state, to wait a predetermined duration, and after the predetermined duration, to provide the second input signal to disable operation of the voltage regulator; and
wherein the central processing unit is configured in the first state to provide a third input signal to an input of the DDR5 DIMM to enable operation of the DDR5 DIMM, and in the second state to provide the third input signal to the input of the DDR5 DIMM to disable operation of the DDR5 DIMM.
