    Abstract: A method includes, in a storage device that includes a non-volatile memory and a volatile memory, maintaining at least one data structure that stores management information used for managing data storage in the non-volatile memory, such that at least a portion of the data structure is stored in the volatile memory. A sequence of journaling chunks is created during operation of the storage device, each journaling chunk including a respective slice of the data structure and one or more changes that occurred in the data structure since a previous journaling chunk in the sequence. The sequence of the journaling chunks is stored in the non-volatile memory. Upon recovering from an electrical power interruption in the storage device, the data structure is reconstructed using the stored journaling chunks.

    Abstract: A System on Chip (SoC) includes a processor, a parity generation circuit, and a dispatcher circuit. The processor is configured to produce store instructions for storing data blocks in a Non-Volatile-Memory (NVM). The parity generation circuit is configured to calculate parity blocks over the data blocks in accordance with a redundant storage scheme, to send the parity blocks to the NVM, and to produce completion notifications with respect to the parity blocks. The dispatcher circuit is configured to dispatch the store instructions to the NVM. The processor is further configured to send one or more parity-barrier instructions that specify synchronization barriers over the store instructions and the parity, and the dispatcher circuit is configured to dispatch the store instructions to the NVM in compliance with the parity-barrier instructions and the completion notifications.

    Abstract: Disclosed are techniques for managing parity information for data stored on a storage device. A method can be implemented at a computing device communicably coupled to the storage device, and include (1) receiving a request to write data into a data band of the storage device, (2) writing the data into stripes of the data band, comprising, for each stripe of the data band: (i) calculating first parity information for the data written into the stripe, (ii) writing the first parity information into a volatile memory, and (iii) in response to determining that a threshold number of stripes have been written: converting the first parity information into smaller second parity information, and (3) in response to determining that the data band is read-verified: (i) converting the second parity information into smaller third parity information, and (ii) storing the smaller third parity information into a parity band of the storage device.
