    Abstract: A method for operating a memory includes receiving a command to program a data value at a memory cell, and an indication of which write mode in a plurality of write modes to use. Write modes in the plurality are characterized by different sets of resistance ranges that correspond to data values stored in the memory cell. The method includes executing a program operation according to the indicated one in the plurality of write modes to program the data value in the memory cell. The plurality of write modes includes a first write mode and a second write mode corresponding to shorter data retention than the first write mode. The first and second write modes are characterized by first and second sets of resistance ranges in the different sets of resistance ranges. The method includes periodically refreshing data values in memory cells storing data in the second write mode.

A three/two dimensional NAND array includes a plurality of pages, which are divided into a plurality of page groups. Access is allowed to memory cells within a first page group of a plurality of page groups in an erase block of the three dimensional NAND array, while access is minimized to memory cells within a second page group of the plurality of page groups in the erase block of the three/two dimensional NAND array. Pages in the same page group are physically nonadjacent with each other in the three/two dimensional NAND array.

    Abstract: A method for managing block erase operations is provided for an array of memory cells including erasable blocks of memory cells in the array. The method comprises maintaining status data for a plurality of sub-blocks of the erasable blocks of the array. The status data indicate whether the sub-blocks are currently accessible and whether the sub-blocks are invalid. The method comprises, in response to a request to erase a selected sub-block of a particular erasable block, issuing an erase command to erase the particular block if the other sub-blocks of the particular erasable block are invalid, else updating the status data to indicate that the selected sub-block is invalid.

    Abstract: A method is provided for managing a file system including data objects. The data objects, indirect pointers and source pointers are stored in containers that have addresses and include addressable units of a memory. The objects are mapped to addresses for corresponding containers. The indirect pointer in a particular container points to the address of a container in which the corresponding object is stored. The source pointer in the particular container points to the address of the container to which the object in the particular container is mapped. An object in a first container is moved to a second container. The source pointer in the first container is used to find a third container to which the object is mapped. The indirect pointer in the third container is updated to point to the second container. The source pointer in the second container is updated to point to the third container.

    Abstract: A method for managing utilization of a memory including a physical address space comprises mapping logical addresses of data objects to locations within the physical address space, and defining a plurality of address segments in the space as an active window. The method comprises allowing writes of data objects having logical addresses mapped to locations within the plurality of address segments in the active window. The method comprises, upon detection of a request to write a data object having a logical address mapped to a location outside the active window, updating the mapping so that the logical address maps to a selected location within the active window, and then allowing the write to the selected location. The method comprises maintaining access data indicating utilization of the plurality of address segments in the active window, and adding and removing address segments from the active window in response to the access data.
