Abstract

An apparatus in accordance with one example includes a battery module in a dual in-line memory module (DIMM) form factor. The battery module is insertable in a DIMM slot of a host device to provide backup power to a plurality of loads of the host device.

Claims

1. An apparatus, comprising:

a battery module in a dual in-line memory module (DIMM) form that adheres to a standard for a DIMM and having a structure that is receivable by a DIMM slot, wherein the battery module is insertable in a DIMM slot of a host device to provide backup power to a plurality of loads of the host device.

2. The apparatus of claim 1, wherein the battery module includes a notch and a plurality of contact pins to connect the battery module to the DIMM slot.

3. The apparatus of claim 2, wherein the plurality of contact pins includes a plurality of power (PWR) pins and a plurality of signal pins.

4. The apparatus of claim 1, wherein the DIMM slot is fixedly coupled to a printed circuit board (PCB) of the host device and wherein the battery module is connected to the PCB via the DIMM slot.

5. The apparatus of claim 4, wherein the battery module is attached to the PCB via at least one of a surface mount connection and a through-hole connection.

6. A system comprising:

a host device supporting at least one load;

a backup power supply in a dual in-line memory module (DIMM) form that adheres to a standard for a DIMM and having a structure that is receivable by a DIMM connector;

a printed circuit board (PCB) including the DIMM connector to receive the backup power supply, wherein the backup power supply is to provide backup power to the at least one load.

7. The system of claim 6, wherein the backup power supply includes at least one notch and a plurality of electrical pins to connect the backup power supply to the PCB via the DIMM connector.

8. The system of claim 7, wherein the DIMM connector includes a latching mechanism to secure the backup power supply via the at least one notch.

9. The system of claim 7, wherein the plurality of electrical pins includes at least a pair of power (PWR) pins and a pair of communication pins.

10. A system comprising:

a host device supporting at least one load;

a backup power supply module in a dual in-line memory module (DIMM) form that adheres to a standard for a DIMM and having a structure that is receivable by a DIMM socket; and

a printed circuit board (PCB) including a plurality of DIMM sockets to receive the backup power supply module and a plurality of DIMMs,

the backup power supply module and a plurality of DIMMs,

wherein the backup power supply module is insertable in a DIMM socket of the plurality of DIMM sockets to provide backup power to the at least one load.

11. The system of claim 10, wherein the at least one load includes the plurality of DIMMs.

12. The system of claim 10, wherein the backup power supply module includes at least one notch and a plurality of contact pins to connect to a DIMM socket of the plurality of DIMM sockets.

13. The system of claim 12, wherein the plurality of contact pins includes at least a pair of power (PWR) pins and a pair of communication pins.

14. The system of claim 10, comprising a second backup power supply module in the DIMM form factor insertable in a second DIMM socket of the plurality of DIMM sockets, wherein the backup power supply module and the second backup power supply module are insertable in parallel in the DIMM socket and the second DIMM socket to provide backup power to the at least one load.

15. The system of claim 10, comprising a backup power control module to determine, based on monitored power, a backup power demand of the at least one load and to provide backup power from the backup power supply module to the at least one load.
