Assignee: WESTERN DIGITAL TECHNOLOGIES, INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 11:
12. A device, comprising:
a processor;
a memory comprising a Persistent Memory Region (PMR) configured to operate under multiple protocols through a single interface wherein a first protocol is a Non-Volatile Memory Express (NVMe) protocol and a second protocol is a Secure Digital Express (SDX) protocol; and
a protocol-switching logic configured to direct the processor to:
initialize the device; and
determine a protocol for use with the device:
wherein if the determined protocol is an NVMe protocol:
a PMR usage threshold is determined;
data associated with the PMR is loaded; and
the device is operated under the determined NVMe protocol;

wherein if the determined protocol is an SDX protocol, the PMR is operated under the SDX protocol;
wherein the PMR is configured to provide performance enhancements under the SDX protocol;
wherein the device is configured to physically couple with multiple host-computing devices; and
wherein the device is further configured to be hot-swappable between multiple host-computing devices.
