    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 translation: 数据文件在具有物理存储器单元块的通常类型的闪存系统的连续逻辑地址空间接口（LBA接口）的一个或多个逻辑块内被分配地址。 该分配可以由主机设备完成，主机设备通常但不一定生成数据文件。 以减少物理存储器块内的文件数据的分段量的方式控制包含任何一个文件的数据的逻辑块的数量，从而保持良好的存储器性能。 响应于学习与其连接的存储器的物理特性，主机可以配置地址空间的逻辑块。

    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. A type of memory block is selected to receive additional data of a file that depends upon the types of blocks into which data of the file have already been written. Blocks containing data are selected for reclaiming any unused capacity therefrom by a process that selects blocks in order starting with those containing the least amount of valid data.

    Abstract: A multi-later memory and method for operation is disclosed. The memory includes three or more layers, where each layer is made up of flash memory cells having a greater bit per cell storage capacity than then prior layer. The method may include the steps of directing host data directly into a first or second layer of the multi-layer memory upon receipt depending on a condition of the data. The method may also include copying data within a respective layer in a data relocation operation to generate more free blocks of memory so that data preferably stays within each layer, as well as transferring data from one layer to the next higher bit per cell layer when layer transfer criteria are met.
