Abstract: Instead of incorporating a single interface towards the host for transferring data, utilizing a designated write-only storage logging device. The write-only storage logging device can accept sequential streams and automatically overwrite. The controller will read the log material in a secure manner using a different and separate physical connection than the one used for write. The storage device may have LBA ranges that work as write-only as well as other LBA ranges, which are normal (both reads and writes are enabled). Both options will allow for a traditional file system as well as sharing the storage, but will still protect the log areas that would be used for events that should not be read out.

Abstract: A vehicle battery includes at least one battery cell and a battery controller for charging the at least one battery cell via a power interface of the vehicle battery. The vehicle battery further includes a battery memory and a data interface to transfer data between the battery memory and a data device external to the vehicle. A data storage controller of the vehicle battery transfers, via the data interface, data between the battery memory and the data device while the vehicle battery is removed from the vehicle. In one aspect, the data device performs at least one of transferring data from a battery memory to a memory of the data device and transferring data from the memory of the data device to the battery memory while the data device is physically connected to the vehicle battery.

Abstract: Aspects of a storage device are provided that apply advanced thermal throttling with multi-tier extreme thermal throttling. Initially, a controller determines whether a first temperature measurement indicates that a temperature of the memory meets a first thermal threshold associated with a first-tier extreme thermal throttling or a second thermal threshold associated with a second-tier extreme thermal throttling. Subsequently, the controller enables the first-tier extreme thermal throttling when the temperature measurement indicates that the temperature of the memory meets the first thermal threshold, or the controller enables the second-tier extreme thermal throttling when the temperature measurement indicates that the temperature of the memory meets the second thermal threshold. The controller then determines whether a second temperature measurement indicates that the temperature of the memory has decreased to avoid thermal shutdown of the storage device.

Abstract: During operation of a data storage device, a controller of the data storage device may initiate read/write operations based on workloads provided by a host device. When initiating the read/write operations, power consumption and the data rate of the data storage device are generally high. Over time, the data rate corresponding to the workload decreases. Thus, the power consumption may be decreased to correspond with the decreased data rate. In order to maintain a high efficiency while decreasing an amount of power utilized, the controller may duty cycle the data storage device to operate between performance states to maintain a high data rate while decreasing power consumption.

Abstract: Methods and apparatus for precise power cycle management in data storage devices are provided. One such apparatus is a data storage device that includes a non-volatile memory (NVM) and a processor coupled to the NVM. In such case, the processor is configured to determine a first peak power for a first power phase, operate the DSD at a first DSD power consumption that is less than the first peak power for the first power phase, determine a second peak power for a second power phase based on a residual power equal to a difference between a preselected average power threshold and the first DSD power consumption, and operate the DSD at a second DSD power consumption that is less than the second peak power for the second power phase.

Abstract: Systems, methods, and data storage devices for secured failover access through data storage device side channels are described. Storage devices may include a storage interface and one or more side channels, such as control bus and debug bus interfaces. The different interfaces may use different interface protocols and physical interface connections configured for different types of commands to the data storage device. When a failure of the storage interface occurs, the data storage device may receive a failover message through one or more side channels to reconfigure the side channel interface to receive, execute, and return a response for host storage commands targeting host data on the storage medium.

Abstract: In a storage system having a plurality of solid state drives (SSDs), the performance of propagating data from a primary device to each secondary device may be improved using a dedicated high speed data channel in which data and commands associated with the data is sent from an upstream SSD to a downstream SSD. The data is also sent to the downstream SSD after a minimum amount of data has been programmed to the upstream SSD. The downstream SSD begins programming the data to its own memory device after receiving the data. The programming of data to each SSD of the storage system may be in parallel and at least partially concurrent with each other. Data, commands, and control messages may be sent an upstream SSD via a serial bus or a universal asynchronous receiver-transmitter channel, such that the downstream data paths and the upstream data paths are distinct.

The at least two additional portions have reflectivity substantially lower than the first reflectivity. The at least one processor is further configured to classify the particular object as a vehicle, based on a spatial relationship and a reflectivity relationship between the first portion and the at least two additional portions.

Abstract: A data storage device having improved protections for in-flight data during a safety event, such as an autonomous-driving-vehicle collision. In an example embodiment, in response to a distress-mode indication signal, the device controller operates to prioritize more-recent data with respect to older counterparts of the same data stream for flushing from the volatile-memory buffers to the non-volatile memory. In addition, the device controller may operate to positively bias the flushed data towards better survivability and/or more-reliable routing.

Abstract: Aspects of a storage device are provided which apply advanced thermal throttling in response to temperature changes based on multiple thermal power states for different types of cells, such as SLCs and MLCs. Initially, a controller determines that a temperature of the memory meets a thermal throttling threshold of a plurality of thermal throttling thresholds. Subsequently, the controller transitions into a thermal power state of a plurality of thermal power states when the temperature meets the thermal throttling threshold. The controller applies a thermal mitigation configuration associated with the thermal power state. The controller then determines that the temperature of the memory has reached a thermal equilibrium in the thermal power state based on the thermal mitigation configuration. Storage device performance is thus improved through advanced thermal throttling without compromising data integrity.
