Abstract: Storage devices are described herein that are capable of communicating with host-computing devices using multiple protocols. These Multi-Protocol Storage Devices (MPSDs) can be configured to utilize a persistent memory region (PMR) across a variety of protocols. Often, one of these protocols is the Non-Volatile Memory express (NVMe) protocol which provides for the ability to utilize and manage a PMR within the storage device. Other protocols may not have native support for PMR like the NVMe protocol does. Therefore, MPSDs are disclosed that may determine which protocol is in use in response to an initialization event and adjust the use of the PMR as needed based on the determined protocol. These adjustments may allow for the direct access of the PMR as an extension of general memory storage or may be configured to provide increased performance of the storage device overall. These storage devices may be hot-swappable between numerous host-computing systems.

Abstract: A SD Card including, in one implementation, a memory array, a controller coupled to the memory array, and a bus for transferring data between the memory array and a host device in communication with the SD Card. The controller is configured to perform background maintenance operations on the memory array during execution of a read command received from the host device.

Abstract: Apparatus, systems, methods, and computer program products for buffering storage device data in a host memory buffer (HMB) are presented. A non-volatile memory and a controller are in communication with a non-volatile memory. A controller is configured to receive an input/output (I/O) operation including data. A controller is configured to transmit at least a portion of data to an HMB of a host device separate from a non-volatile memory and a controller for storage until a trigger event occurs.
