摘要： A tiered memory system includes a memory controller for a primary memory and a secondary memory, where the secondary memory is used as a cache for the primary memory. The memory controller is configured to cause redundant data that is stored in the primary memory of the memory system to be stored in first memory locations of the secondary memory. The controller causes data that is not stored in the primary memory to be stored in second memory locations of the secondary memory. The second memory locations have at least one of lower bit error rate and higher access speed than the first memory locations.

摘要： Method and apparatus for managing data in a memory, such as a flash memory array. In accordance with some embodiments, a first block of data is written to a group of memory cells at a first memory location in single-level cell (SLC) mode. The first block of data is copied from the first memory location to a group of memory cells at a second memory location to provide a backup copy of the first block of data during a protected mode of operation. A second block of data is subsequently overwritten to the group of memory cells at the first memory location so that the first memory location stores both the first and second blocks of data in multi-level cell (MLC) mode.

摘要： A data structure is formed that references a garbage collection metric for each of a plurality of associated garbage collection units of a flash memory device. Each garbage collection metric is based on one or more device state characteristics of the associated garbage collection unit. In response to a threshold change in the one or more device state variables, a region of interest within the data structure is sorted based on the garbage collection metrics. One or more garbage collection units are selected for garbage collection operations from the sorted region of interest.

摘要： A first data set is written to first memory units identified as having a higher data reliability and a second data set is written to second memory units identified as having a lower data reliability than the first memory units. In some cases, the second data set may include metadata or redundancy information that is useful to aid in reading and/or decoding the first data set. The act of writing the second data set increases the data reliability of the first data set. The second data set may be a null pattern, such as all erased bits.

摘要： A new segment of data is copied to a volatile, primary cache based on a host data read access request. The primary cache mirrors a first portion of a non-volatile main storage criterion is determined for movement of data from the primary cache to a non-volatile, secondary cache that mirrors a second portion of the main storage. The criterion gives higher priority to segments having addresses not yet selected for reading by the host. In response to the new segment of data being copied to the primary cache, a selected segment of data is copied from the primary cache to the secondary cache in response to the selected segment satisfying the criterion.

摘要： Method and apparatus for enhancing reliability and integrity of data stored in a non-volatile memory, such as in a solid-state drive (SSD) having an array of flash memory cells. In accordance with various embodiments, a controller is adapted to harden data stored in a first location of said memory in relation to a detected loss of retention characteristics of the first location. In some embodiments, the data are hardened by storing redundancy information associated with said data in a second location of said memory. The redundancy information can be a redundant set of the data or higher level error correct codes (ECC). The hardened data can be recovered to the host during a read operation by accessing the data stored in both the first and second locations.

摘要： Method and apparatus for handling data in a data storage device. In accordance with some embodiments, a memory space with a plurality of garbage collection units (GCUs) that are each arranged into pages of memory that store user data identified by logical addresses (LAs) and each GCU has a metadata region that stores metadata that correlates the LAs with physical addresses (PAs). A header region in each page of memory stores a bitmask and a sequence map of the LAs in each page that are used by a log manager to creates a bitmask table stored in a first cache and a hierarchical log stored in a second cache. The bitmask table and hierarchical log are used to determine when the LAs stored in the selected GCU are stale, and update the bitmask for each page in the selected GCU after the stale data has been erased.
