    Abstract: A storage device includes storage circuitry and multiple memory blocks. The multiple memory blocks are arranged in an array, and each of the memory blocks includes multiple memory cells. A maximal number of programming cycles that a memory block of the multiple memory blocks sustains depends on a distance of the memory block from an edge of the array. The storage circuitry is configured to apply to the memory blocks programming cycles so that a number of programming cycles that can be applied to a respective memory block is based on a respective distance of the respective memory block from the edge of the array.

    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.

    Abstract: A controller includes an interface and a processor. The interface is configured to communicate with a nonvolatile memory including multiple memory cells organized in multiple memory blocks that each includes multiple Word Lines (WLs). The processor is configured to store first data in one or more WLs of a memory block, the first data occupies less than a maximal number of WLs available in the memory block, to calculate redundancy data over the first data and store the redundancy data in a dedicated memory, to program second data to a selected WL of the memory block that was not programmed with the first data, to check a programming status resulting from the programming of the selected WL, and in response to identifying that programming the second data to the selected WL has corrupted at least part of the first data, to recover the first data using the redundancy data.

    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.
