  • Publication number: 20130326116
    Abstract: 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.

  • Publication number: 20130322169
    Abstract: 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.

  • Publication number: 20130326115
    Abstract: 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.

  • Publication number: 20130258770
    Abstract: 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.

  • Publication number: 20130007380
    Abstract: A first cumulative data transfer over a first time window from an intermediary module to a data storage media is determined. The intermediary module is coupled between a host interface and the data storage media. An activity rate from the intermediary module to the data storage media is limited for one or more subsequent time windows if the first cumulative activity rate exceeds a threshold value that impacts life of the data storage media.

  • Publication number: 20130007543
    Abstract: Representative locations of a non-volatile, solid-state memory of an apparatus store characterization data. An event during which elapsed time is not measured by the apparatus is determined. In response to the event, temporal degradation of the non-volatile, solid-state memory during the event is estimated based on electrical characteristics of the representative locations.

  • Publication number: 20120300554
    Abstract: Method and apparatus for sanitizing a non-volatile memory, such as a flash memory array. In accordance with various embodiments, a memory cell is sanitized by using a write circuit to accumulate charge on a floating gate of the cell to a level such that application of a maximum available read sensing voltage to a control gate of the cell is insufficient to place the cell in a conductive state.

  • Publication number: 20120278579
    Abstract: Method and apparatus for self-initiated secure erasure of data from a non-volatile memory, such as a solid state drive (SSD). In accordance with various embodiments, the memory is operated in communication with a host device. A self-initiated, non-destructive secure erasure of the data stored in the memory is carried out responsive to a detection of an unauthorized power down event associated with the memory.

  • Publication number: 20120278564
    Abstract: Method and apparatus for securely erasing data from a non-volatile memory, such as but not limited to a flash memory array. In accordance with various embodiments, an extended data set to be sanitized from the memory is identified. The extended data set includes multiple copies of data having a common logical address and different physical addresses within the memory. The extended data set is sanitized in relation to a characterization of the data set. The data sanitizing operation results in the extended data set being purged from the memory and other previously stored data in the memory being retained.

  • Publication number: 20120198312
    Abstract: 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.

  • Publication number: 20120124273
    Abstract: Completion times of data storage operations targeted to a non-volatile, solid-state memory device are measured. Wear of the memory device is estimated using the measured completion times, and life cycle management operations are performed to affect subsequent wear of the memory device in accordance with the estimated wear. The life cycle management may include operations such as wear leveling, predicting an end of service life of the memory device, and removing worn blocks of the memory device from service.

  • Publication number: 20100091403
    Abstract: A data storage device is disclosed. In one embodiment, the data storage device has a maximum storage capacity and is initially limited to providing access to a limited amount of data storage capacity that is less than the maximum data storage capacity. The size of the limited amount of data storage capacity is variable based on an indication of how much of a collection of advertising material has been viewed. In one embodiment, a host system manages a transfer of all or a portion of the collection of advertising material to a storage location on the data storage device. In one embodiment, the same host system manages adjustments to the size of the limited amount of data storage capacity based on how much of the collection of advertising materials has been consumed.
