    Abstract: A flash memory system having unequal number of memory die and method for operation are disclosed. The memory system includes a plurality of flash memory die distributed unevenly among different control lines, such that there are an unequal number of die between control lines. A total physical capacity of the plurality of flash memory die is greater than a total logical capacity such that the memory system is over provisioned with physical capacity. A logical address splitter directs data received from a host system and associated with host logical block addresses such that each control line only receives data associated with predetermined host logical block address ranges and directs the data such that a ratio of physical capacity to logical capacity is equal among each of the control lines, regardless of the different number of die and associated different physical capacity per control line.

    Abstract: A multi-layer memory and method for operation is disclosed. The memory includes an interface, at least one flash memory die having a plurality of layers and a controller. The controller is configured to select an appropriate one of a predetermined number of program cycles for programming a fixed amount of host data, and for carrying out maintenance operations in one or more of the layers sufficient to permit a next host data write operation. The controller calculates an interleave ratio of maintenance operations to host data programming operations in each of the layers used in the determined programming cycle so that creation of free space is interspersed with host data writes in a steady manner during execution of the determined programming cycle.

    Abstract: A multi-later memory and method for operation is disclosed. The memory includes at least one flash memory die having multiple layers and a controller configured to execute block reclaim operations in a layer of the flash memory die until a net gain of at least one additional free block has been made in the layer. The method may include relocating data from reclaim blocks to relocation blocks within the same layer, or within a same partition in the same layer until a net gain of one free block has been achieved and an integer number of relocation blocks has been filled with relocated data. The method may also include moving data from reclaim blocks in a first layer into destination blocks in a second layer until a net gain of at least one free block has been achieved in the first layer.

    Abstract: Host system data files are written directly to a large erase block flash memory system with a unique identification of each file and offsets of data within the file but without the use of any intermediate logical addresses or a virtual address space for the memory. Directory information of where the files are stored in the memory is maintained within the memory system by its controller, rather than by the host. Each data file is uniquely identified in a file directory, which points to entries in a file index table (FIT) of data groups that make up the file and their physical storage locations in the memory.

    Abstract: Data files are assigned addresses within one or more logical blocks of a continuous logical address space interface (LBA interface) of a usual type of flash memory system with physical memory cell blocks. This assignment may be done by the host device which typically, but not necessarily, generates the data files. The number of logical blocks containing data of any one file is controlled in a manner that reduces the amount of fragmentation of file data within the physical memory blocks, thereby to maintain good memory performance. The host may configure the logical blocks of the address space in response to learning the physical characteristics of a memory to which it is connected.

    Abstract: In a nonvolatile memory system that includes a block-erasable memory array, records are individually maintained for certain classifications of blocks. One or more lists may be maintained for the blocks, an individual list ordered according to a descriptor value. Such ordered lists allow rapid identification of a block by descriptor value.
