Abstract: A multi-function universal serial bus (USB) device may include a plurality of USB interfaces, including a first USB interface and a second USB interface. The USB device may include a plurality of memories including a first memory and a second memory. The USB device may include a controller coupled to the first memory and the second memory, the controller configured to: identify which one of the first USB interface and the second USB interface is coupled to a host device; and perform operations on one of the first memory or the second memory based on which one of the first USB interface and the second USB interface is identified to be coupled to the host device.

Abstract: A data storage device includes a memory device and a controller coupled to the memory device. The controller is configured to operate under at least a first device protocol and a second device protocol, where the first and second device protocols have different endurance and protection requirements. When data is programmed to the memory device using the first device protocol, but is read from the memory device using the second device protocol, the differing endurance and protection requirements may cause issues in reading the data. In order to alleviate the issues, during idle time of the second device protocol, the controller may program the data using the endurance and protection requirements of the second device protocol to a different portion of the memory device so that the data may be read using either or both device protocols with the appropriate recovery information.
