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： Apparatus and method for data management in a memory, such as but not limited to a flash memory array. In accordance with some embodiments, a plurality of data sets in a memory are identified as having a common data content and different physical addresses in the memory. A selected one of the data sets is marked as valid data and the remaining data sets are marked as stale data responsive to evaluation of at least one variable parameter associated with the physical addresses at which the data sets are respectively stored.

摘要： Method and apparatus for managing data in a memory, such as but not limited to a flash memory. In accordance with some embodiments, a memory is provided with a plurality of addressable data storage blocks which are arranged into a first set of garbage collection units (GCUs). The blocks are rearranged into a different, second set of GCUs responsive to parametric performance of the blocks.

摘要： Method and apparatus for managing data in a memory, such as a flash memory array. In accordance with various embodiments, data are stored in a first location in a memory, and read from the first location a selected number of times. At least one parameter associated with the first location is measured after the data are read the selected number of times. The data are thereafter migrated to a second location in the memory responsive to the measured parameter indicating a presence of read disturbance in the data in the first location.

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 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.
