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 filing 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 filing system to ensure that one or more clusters (or one or more sectors within a cluster) are not copied from one location to another location in the memory during a garbage collection cycle. As a result, some unnecessary operations (e.g., copying data) which are conventionally performed can be avoided and system performance can be enhanced.

Abstract: A non-volatile memory system is organized in physical groups of physical memory locations. Each physical group (metablock) is erasable as a unit and can be used to store a logical group of data. A memory management system allows for update of a logical group of data by allocating a metablock dedicated to recording the update data of the logical group. The update metablock records update data in the order received and has no restriction on whether the recording is in the correct logical order as originally stored (sequential) or not (chaotic). Eventually the update metablock is closed to further recording. One of several processes will take place, but will ultimately end up with a fully filled metablock in the correct order which replaces the original metablock. In the chaotic case, directory data is maintained in the non-volatile memory in a manner that is conducive to frequent updates. The system supports multiple logical groups being updated concurrently.

Abstract: In a memory system having multiple erase blocks in multiple planes, a selected number of erase blocks are programmed together as an adaptive metablock. The number of erase blocks in an adaptive metablock is chosen according to the data to be programmed. Logical address space is divided into logical groups, a logical group having the same size as one erase block. Adaptive logical blocks are formed from logical groups. One adaptive logical block is stored in one adaptive metablock.

Abstract: A method and system for permitting host write operations in one part of a flash memory concurrently with another operation in a second part of the flash memory is disclosed. The method includes receiving data at a front end of a memory system, selecting at least one of a plurality of subarrays in the memory system for executing a host write operation, and selecting at least one other subarray in which to execute a second operation. The write operation and second operation are then executed substantially concurrently. The memory system includes a plurality of subarrays, each associated with a separate subarray controller, and a front end controller adapted to select and initiate concurrent operations in the subarrays.

Abstract: Files that are mapped to a logical address range by a host become logically fragmented prior to being sent to a memory system. Subsequently, the logically fragmented portions are reassembled when they are stored in blocks in the memory system. The host supplies information to the memory system regarding file-to-logical mapping of data prior to sending the data. The memory selects storage locations for the data based on the files to which the data belong.

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: A data storage device is provided. A disk device is combined with a non-volatile memory device to provide much shorter write access time and much higher data write speed than can be achieved with a disk device alone. Interleaving bursts of sector writes between the two storage devices can effectively eliminate the effect of the seek time of the disk device. Following a non-contiguous logical address transition from a host system, the storage controller can perform a look-ahead seek operation on the disk device, while writing current data to the non-volatile memory device. Such a system can exploit the inherently faster write access characteristics of a non-volatile memory device, eliminating the dead time normally caused by the disk seek time.

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. The file based interface between the host and memory systems allows the memory system controller to utilize the data storage blocks within the memory with increased efficiency.
