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: 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 controller communicates with a plurality of multi-chip memory packages. Each multi-chip memory package comprises a plurality of memory dies, each having a respective plurality of memory blocks, some of which are good and some of which are bad. The controller determines a number of good blocks in each memory die. Based on the determined number of good blocks in each memory die, the controller selects a memory die from each of the multi-chip memory packages to access in parallel, wherein the selected memory dies are not necessarily all in the same relative position in each multi-chip package. The controller then creates a metablock from a set of good blocks from each of the selected memory dies, wherein a maximum number of metablocks that can be created across the selected memory dies is determined by a lowest number of good blocks in the selected memory dies.

Abstract: A method and system writes data to a memory device including dynamic assignment of logical block addresses (LBAs) to physical write blocks. The method includes receiving a request to write data for a logical block address within an LBA range to the memory device. The method assigns the LBA range to a particular write block exclusively or non-exclusively, depending on the existence of previously assigned write blocks and the availability of unwritten blocks. A data structure may be utilized to record the recent usage of blocks for assigning non-exclusive write blocks. An intermediate storage area may be included that implements the dynamic assignment of LBA ranges to physical write blocks. Data in the intermediate storage area may be consolidated and written to the main storage area. Lower fragmentation and write amplification ratios may result by using this method and system.

Abstract: Methods of maintaining an address table for mapping logical addresses to physical addresses include continuously consolidating main address maps and an update address map, and periodically compacting the update address map. Consolidating includes selecting a main address map, reading valid mapping entries from the main and update address maps, constructing a mapping set including the valid mapping entries, and writing the mapping set to a second main address map. The update address map is compacted if a criterion is met, and includes copying the valid mapping entries to an unwritten block or metablock and assigning the unwritten block or metablock as a new update address map. The length of consolidation may depend on the average length of compacted mapping entries following a compaction operation. Increased performance due to lower maintenance overhead may result by using these methods.

Abstract translation: 维护用于将逻辑地址映射到物理地址的地址表的方法包括连续合并主地址映射和更新地址映射，并且周期性地压缩更新地址映射。 合并包括选择主地址映射，从主地址映射和更新地址映射读取有效的映射条目，构建包括有效映射条目的映射集，以及将映射集写入第二主地址映射。 如果满足标准，则更新地址映射被压缩，并且包括将有效的映射条目复制到未写入的块或元区块，并将未写入的块或元区块分配为新的更新地址映射。 合并的长度可能取决于压实操作之后压实的映射条目的平均长度。 通过使用这些方法可能导致由于较低的维护开销而导致的性能提高。

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 method and system for interfacing a system operating through a logical address space with a direct file storage (DFS) medium is disclosed. The method includes receiving data associated with addresses in a logical block address (LBA) format from a host system and generating file objects manageable by the DFS medium based on a determination of the correlation of the LBA data to host file data. The memory system includes non-volatile memory using the DFS format, an interface for receiving LBA format data, and a controller configured to communicate with the host via an LBA interface and generate file objects from the LBA format data correlated to the host application files usable by the memory system.
