Abstract: A change in the amount of data to be stored that results from various encoding, compression, encryption or other data transformation algorithms, is handled by individually identifying distinct units of the transformed data and storing such units in physical succession within storage blocks of a memory system such as flash memory. The data being stored may come from a host system external to the memory system or from an application running on a processor within the memory system.

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: A method and system for reading data from a non-volatile mass storage device is provided. The method includes, performing logical configuration for the non-volatile mass storage device, wherein file data is allocated addresses in a virtual logical address space; and data identified by virtual logical addresses is read by a host system. The system includes a file storage segment that reads and writes data on a file-by-file basis, allowing a host system to access data from the non-volatile mass storage device using a file interface format; and a logical interface segment that allows the host system to access data using logical addressing, wherein the host system is unaware of a storage format under which data is stored on a file-by-file basis.

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.

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: In a non-volatile memory array, scheduling of reclaim operations to occur before a shortage of erased blocks arises avoids extended periods of reclaim that could exceed a time limit. A memory controller uses information regarding the data stored in the memory array to estimate the additional host data that may be programmed and the reclaim operations to be performed and schedules the reclaim operations to be evenly distributed between write operations until the memory is full.

Abstract: Techniques for managing data in a non-volatile memory system (e.g., Flash Memory) are disclosed. A controller can use information relating to a host's file system, which is stored by the host on non-volatile memory, to determine if one or more clusters (or sectors with clusters) are currently allocated. The controller can use the information relating to the host's file system to identify when the host is sending data to the next free cluster and to store such data in a sequential format by copying data from other locations in the non-volatile memory.

Abstract: A dual media storage device is provided. Two separate non-volatile mass storage devices, one having a faster access time and a lower capacity than the other, are combined into a single system. A storage controller can direct the flow of data into one device or the other, depending upon various conditions, which might include one mass storage device being unavailable or for certain caching schemes.

Abstract: Systems and methods for allocating blocks at a reprogrammable non-volatile mass storage system are disclosed. Generally, a controller identifies a group of data to be written to a block at the mass storage system, and allocates one of a new block or a partial block to the identified group of data based on whether a total unprogrammed capacity in partial blocks of the mass storage system exceeds an amount of valid data in obsolete blocks of the mass storage system. In one implementation, the identifier group of data may be associated with a single file.
