    摘要: Enhanced write performance for non-volatile memories including a memory system that includes a receiver for receiving a data rate of a data sequence to be written to a non-volatile flash memory device. The memory system also includes a physical page selector for selecting a physical address of an invalid previously written memory page from a group of physical addresses of invalid previously written memory pages located on the non-volatile memory device, and for determining if the number of free bits in the invalid previously written memory page at the selected physical address is greater than or equal to the data rate. The memory system also includes a transmitter for outputting the selected physical address of the invalid previously written memory page, the outputting in response to the physical page selector determining that the number of free bits is greater than or equal to the data rate.

    摘要: Discarded memory devices unfit for an original purpose can be reclaimed for reuse for another purpose. The discarded memory devices are tested and evaluated to determine the level of performance degradation therein. A set of an alternate usage and an information encoding scheme to facilitate a reuse of the tested memory device is identified based on the evaluation of the discarded memory device. A memory chip controller may be configured to facilitate usage of reclaimed memory devices by enabling a plurality of encoding schemes therein. Further, a memory device can be configured to facilitate diagnosis of the functionality, and to facilitate usage as a discarded memory unit. Waste due to discarded memory devices can be thereby reduced.

    摘要: Techniques are presented that include determining, for data to be written to a nonvolatile memory, a location in the nonvolatile memory to which the data should be written based at least on one or more wear metrics corresponding to the location. The one or more wear metrics are based on measurements of the location. The measurements estimate physical wear of the location. The techniques further include writing the data to the determined location in the nonvolatile memory. The techniques may be performed by methods, apparatus (e.g., a memory controller), and computer program products.
