Abstract: A storage device may recover from an uncorrectable read failure in a control block. The storage device includes a memory device divided into blocks. The blocks on the memory device may include control blocks for storing control information for accessing host data. A controller on the storage device may identify when an uncorrectable read failure occurs in a first control block. The controller may quarantine the first control block and notify a host device of the uncorrectable read failure. Based on a response from the host device, the controller may recover the storage device to operate in a normal mode such that a recovered storage device excludes the first control block from use.

Abstract: A storage device postpones entry into a read-only mode due to faulty blocks that cannot be written to on a memory device. The memory device is divided into blocks. Blocks used for storing host data are placed in a main area pool, blocks used for storing host data and for peak write operations are placed in a burst pool, and blocks used for storing control information are placed in the control pool. A controller executes a read-only mode extension protocol to determine when a number of faulty blocks in the main area pool, control pool, or burst pool is approaching a threshold for placing the storage device in a read-only mode. If the storage device is approaching the read-only mode, the controller reduces and/or repurposes a number of the blocks used for storing host data in the burst pool to prevent the storage device from entering the read-only mode phase.

In some embodiments, the controller can be configured to initiate a data operation, such as an authentication or data accessibility operation, a data security operation, etc., for example, in addition to or instead of a disk operation.

Abstract: A memory block recovery process is used to review and recover memory blocks of a memory device that have potentially been misidentified as bad blocks. The memory block recovery process is initiated when a threshold number of entries in a failed memory block list is exceeded. During the memory block recovery process, the failed memory block list is analyzed to determine whether there is any correlation between memory blocks that failed programming operations and memory blocks that were programmed prior to the memory block failing its programming operation. If there is a correlation, an independent program operation is performed on each memory block that failed its programming operation. If the independent programming operation on the memory block is successful, the memory block is reclaimed and the prior programmed memory block is identified as a bad block.

Abstract: Register banks are used to allow for fast beam switching in a phased array system. Each beam forming channel is associated with a register bank containing M register sets for configuring such things as gain/amplitude and phase parameters of the beam forming channel. The register banks for all beam forming channels can be pre-programmed and then fast beam switching circuitry allows all beam forming channels across the array to be switched to use the same register set from its corresponding register bank at substantially the same time, thereby allowing the phased array system to be quickly switched between various beam patterns and orientations. Active power control circuitry may be used to control the amount of electrical power provided to or consumed by one or more individual beam forming channels such as to reduce DC power consumption of the array and/or to selectively change the effective directivity of the array.

Abstract: A low power crystal oscillator circuit has a high power part and a low power part. Crystal oscillation is initialized using the high power part. An automatic amplitude control circuit includes a current subtractor that decreases current in the high power part as an amplitude of the crystal oscillation increases. A current limiting circuit may limit current in the low power part in order to further reduce power consumption by the low power crystal oscillator circuit. Additionally, an automatic amplitude detection circuit may turn off the high power part after the amplitude of the crystal oscillation reaches a predetermined level in order to further reduce power consumption of the low power crystal oscillator circuit, and may turn back on the high power part after the amplitude of the crystal oscillation reaches a second predetermined level in order to maintain the crystal oscillation.

Abstract: A read to a wordline can cause a read disturb error on neighboring wordlines. Instead of scanning the entire memory to identify wordlines that have a read disturb problem, a localized read scan approach can be used. In this approach, the memory is organized into several zones, where each zone contains several wordlines. The number of reads in each zone is tracked, and, after a certain number of reads, the data in the zone is read. If the error rate of the data exceeds a threshold, the data is relocated to another area of the memory.

Abstract: Methods for storing control information for memory operations within spare physical blocks. During formatting of a data storage device, spare memory blocks may be identified within memory dies and placed into a spare block pool. Upon initiation of a block exchange event for a control block, a controller determines whether a spare block is available in the spare block pool. When a spare block is available, data from the control block is copied to the spare block to generate a debug block. The control block may be a MasterIndexPage block. When a spare block is not available, the controller may erase information stored in an oldest debug memory block and copy data from the control block to the oldest debug memory block.

Abstract: Some areas (e.g., boundary wordlines) in a block of memory can be more error prone than others. Typically, errors in these areas are not detected until after the entire block is programmed. Handling such errors then can result in performance penalties and large data relocations. With the embodiments presented herein, a two-stage programming operation is provided. In the first stage, only the error-prone areas of the block are programmed, and a check is made to determine if an error occurred in that programming. In the second stage, the remaining portions of the block are programmed, but that only occurs after it is determined that the error-prone areas have been programmed successfully. Detecting and dealing with errors in the error-prone areas before the entire block is programmed avoid the performance penalties and large data relocations noted above.

Abstract: A method includes obtaining k-space data acquired by an MRI scanner from a single channel body coil utilizing a multi-shot EP-DWI pulse sequence and sampling the k-space data for a plurality of shots so that for each shot both a central k-space is fully sampled to form a central calibration region and an outer k-space is partially sampled by a factor equal to a number of shots. The method includes reconstructing an initial fully sampled k-space estimate for each shot utilizing both partial Fourier constant sampling and projection on convex sets reconstruction, wherein the plurality of shots is treated as a plurality of channels for filling in missing k-space for a respective shot. The method includes utilizing a low-rank regularization algorithm in an iterative manner to generate a reconstructed image for each shot, wherein the initial fully sampled k-space estimate for each shot is utilized as an initial guess.
