Abstract: Systems, methods and/or devices are used to enable locality grouping during garbage collection of a storage device. In one aspect, the method includes, at a storage controller for the storage device: performing one or more operations for a garbage collection read, including: identifying one or more sequences of valid data in a source unit, wherein each identified sequence of valid data has a length selected from a set of predefined lengths; and for each respective sequence, transferring the respective sequence to a respective queue of a plurality of queues, in accordance with the length of the respective sequence; and setting a global flag to flush all open queues; and performing one or more operations for a garbage collection write, including: identifying open respective queues for writing to a destination unit; and writing from the open respective queues to the destination unit.

Abstract: A memory system that includes a memory array and a memory controller manages power consumption by maintaining a variable credit value that reflects the amount of power available to the memory system. The variable credit value may be increased periodically up to a limit. When a power-consuming operation is performed, the variable credit value is reduced to reflect the power used.

Abstract: A memory controller for a memory card such as an SD card with an additional host interface such as a USB interface comprises a duplicate SD interface. Embodiments with two SD interfaces may also comprise a card reader controller chip that can be turned off by the memory controller when the USB interface is not needed. Incorporation of the additional SD interface in the controller allows for an economical or off the shelf card reader controller to be employed.

Abstract: The present system for recording vehicle-related data does not involve an elaborate installation procedure and thus may be routinely transferred from one vehicle to the next. The system has a recording module and at least on sensor module. The recording module has a wireless receiver, a processor, a vehicle interface assembly, and a data processor interface. The vehicle interface assembly enables the recording module to detachably connect to the vehicle. The sensor modules have a sensor, a processing subsystem, and a wireless transmitter. The wireless transmitter of a sensor module communicates with the wireless receiver of the recording module. Also disclosed is a method of recording vehicle related data.
