Abstract: Apparatus and method for managing data in a processing system, such as but not limited to a data storage device such as a solid-state drive (SSD). A ferroelectric stack register memory has a first arrangement of ferroelectric memory cells (FMEs) of a first construction and a second arrangement of FMEs of a different, second construction arranged to provide respective cache lines for use by a controller, such as a programmable processor. A pointer mechanism is configured to provide pointers to point to each of the respective cache lines based on a time sequence of operation of the processor. Data sets can be migrated to the different arrangements by the controller as required based on the different operational characteristics of the respective FME constructions. The FMEs may be non-volatile and read-destructive. Refresh circuitry can be selectively enacted under different operational modes.

Abstract: A system for use in an aerospace environment includes an array of storage drives each comprising a non-radiation-hardened drive controller, a non-radiation-hardened, non-volatile, storage medium, and a non-radiation-hardened volatile memory. The system includes a radiation-tolerant storage controller coupled to the array. The storage controller provides failure-resistant data redundancy among the storage drives of the array. The system includes a bus host that accesses the array via the storage controller. The storage controller implements security logic and a root-of-trust that provides to the bus host verification of authenticity of the radiation tolerant storage controller and the storage drives.

Abstract: A data storage apparatus includes a disk storage region in which magnetic disks are stored. A carrier mechanism picks up one or more of the magnetic disks and moves them to and from the disk storage region. A data access device of the apparatus includes a structure to receive the one or more magnetic disks from the carrier mechanism and spins the magnetic disks in place. One or more actuator arms are operable to move across a same surface of the one or more magnetic disks. Two or more read transducers are mounted to the actuator arms and operable to simultaneously read from the same surface of the one or more magnetic disks. Two or more write transducers are mounted to the actuator arms and operable to simultaneously write to the same surface of the one or more magnetic disks.

Abstract: A data storage system can employ a read destructive memory configured to fill a first cache with a first data set from a data repository prior to populating a second cache with a second data set describing the first data set with the first and second cache each having non-volatile ferroelectric memory cells. An entirety of the first cache may be read in response to a cache hit in the second cache with the cache hit responsive to a data read command from a host and with the first cache being read without a refresh operation restoring the data of the first cache.

Abstract: A data storage system can provide low cost and optimized performance with a cartridge housing multiple separate data storage devices and each of the data storage devices being concurrently engaged by a device player. The device player may have a processor configured to analyze mechanical performance of each data storage device and data performance of data resident in each data storage device.

Abstract: A data storage library includes a number of storage cartridges arranged in a rack accessed by a actuated media player. The actuated media player is adapted to move the along a plane relative to a fixed subset of the storage cartridges in the rack to and to selectively couple to each storage cartridge of the fixed subset to facilitate selective read/write access.

Abstract: An implementation of a system disclosed herein includes a control board including multiple cartridge slots and hardware for coupling each of the multiple cartridge slots to an associated storage cartridge. The system further includes multiple voice coil motor (VCM) actuator components mounted to the control board, each one of the multiple VCM actuator configured to contribute to an electromagnetic interaction that drives movement of an actuator arm within a storage cartridge coupled to one of the multiple cartridge slots.

Abstract: Apparatus and method for selective overwrite protection of data stored in a non-volatile memory (NVM) with fine precision. In some embodiments, a write command is received from a host device to write one or more blocks of data having associated logical addresses to the NVM. A read operation is performed in response to the write command to read a tag value associated with each block. The write command is disallowed in response to the tag value indicating a protected version of the block having the associated logical address is already stored at the selected location. The tag value may be a key version value indicative of a version of an encryption key used to encrypt user data in the data block and whether the block is write-protected.

Abstract: A recording surface of a magnetic disk is divided into first and second zones. A first head of a first actuator arm assembly reads from and/or writes to the first zone exclusively. A second head of a second actuator arm assembly reads from and/or writes to the second zone exclusively. The first and second head are capable of simultaneously reading from and writing to the recording surface.
