    Abstract: Error correction methods for arrays of resistive change elements are disclosed. An array of resistive change elements is organized into a plurality of subsections. Each subsection includes at least one flag bit and a plurality of data bits. At the start of a write operation, all bits in a subsection are initialized. If any data bits fail to initialize, the pattern of errors is compared to the input data pattern. The flag cells are then activated to indicate the appropriate encoding pattern to apply to the input data to match the errors. The input data is then encoded according to this encoding pattern before being written to the array. A second error correction algorithm can be used to correct remaining errors. During a read operation, the encoding pattern indicated by the flag bits is used to decode the read data and retrieve the original input data.

    Abstract: Several embodiments of memory devices and systems having a variable logical memory capacity are disclosed herein. In one embodiment, a memory device can include a plurality of memory regions that collectively define a physical memory capacity and a controller operably coupled to the plurality of memory regions. The controller is configured to advertise a first logical memory capacity to a host device, wherein the first logical memory capacity is less than the physical memory capacity, determine that at least one of the memory regions is at or near end of life, and in response to the determination, (1) retire the at least one of the memory regions and (2) reduce a logical memory capacity of the host device to a second logical memory capacity that is less than the first logical memory capacity.

    Abstract: A method of encoding data on single level or variable multi-level cell storage includes receiving a block of encoded data from an approximation-aware application and at least an importance attribute associated with the block of encoded data; and assigning the block of encoded data to a memory address or a particular region of a memory having at least three precision levels, based at least according to the importance attribute. The importance attribute indicates a relative sensitivity of bits of the block to errors in an output quality from decoding the encoded data. An approximation-aware application can be an image encoding application having a modified entropy encoding step that enables identification and splitting of bits into groupings according to sensitivity to errors.
