摘要： In a memory system with a file storage system, an optimal file handling scheme is adaptively selected from a group thereof based on the attributes of the file being handled. The file attributes may be obtained from a host or derived from a history of the file had with the memory system. In one embodiment, a scheme for allocating memory locations for a write operation is dependent on an estimated size of the file to be written. In another embodiment, a scheme for allocating memory locations for a relocation operation, such as for garbage collection or data compaction, is dependent on an estimated access frequency of the file in question. In this way, the optimal handling scheme can be used for the particular file at any time.

摘要： In a memory with block management system, program failure in a block during a time-critical memory operation is handled by continuing the programming operation in a breakout block. Later, at a less critical time, the data recorded in the failed block prior to the interruption is transferred to another block, which could also be the breakout block. The failed block can then be discarded. In this way, when a defective block is encountered during programming, it can be handled without loss of data and without exceeding a specified time limit by having to transfer the stored data in the defective block on the spot. This error handling is especially critical for a garbage collection operation so that the entire operation need not be repeated on a fresh block during a critical time. Subsequently, at an opportune time, the data from the defective block can be salvaged by relocation to another block.
摘要翻译：在具有块管理系统的存储器中，通过在分组块中继续编程操作来处理在时间紧急的存储器操作期间块中的程序故障。之后，在不太关键的时刻，在中断之前记录在故障块中的数据被传送到另一个块，也可以是分组块。然后可以丢弃失败的块。以这种方式，当在编程期间遇到有缺陷的块时，可以在不丢失数据的情况下处理而不超过指定的时间限制，因为必须现场将存储的数据传送到缺陷块中。这种错误处理对于垃圾收集操作尤其重要，因此在关键时刻不需要在新块上重复整个操作。随后，在适当的时间，来自缺陷块的数据可以通过重新定位到另一个块来进行抢救。

摘要： A re-programmable non-volatile semiconductor memory, such as flash memory, operates to store files with logical addresses including a unique file identifier and offsets of data within the file, termed direct data file storage. Data files generated by a host may be stored directly in such a memory through a file interface. But if a traditional host/memory interface using a continuous logical address space is being used to identify multiple files, the address space is divided into contiguous logical files, and then these files are treated in the same manner as files obtained directly from a host. Both types of interfaces may be included in the same memory system.

摘要： A flash re-programmable, non-volatile memory system is operated to disable foreground execution of housekeeping operations, such as wear leveling and data scrub, in the when operation of the host would be excessively slowed as a result. One or more characteristics of patterns of activity of the host are monitored by the memory system in order to determine when housekeeping operations may be performed without significantly degrading the performance of the memory system, particularly during writing of data from the host into the memory.

摘要： Update data to a non-volatile memory may be recorded in at least two interleaving streams such as either into an update block or a scratch pad block depending on a predetermined condition. The scratch pad block is used to buffered update data that are ultimately destined for the update block. Synchronization information about the order recording of updates among the streams is saved with at least one of the streams. This will allow the most recently written version of data that may exist on multiple memory blocks to be identified. In one embodiment, the synchronization information is saved in a first block and is a write pointer that points to the next recording location in a second block. In another embodiment, the synchronization information is a time stamp.

摘要： In a nonvolatile memory with a block management system, data written to blocks include host write data and also system control data for managing the blocks. When a block is full or no longer accepting data, it is closed after valid versions of the data on it are relocated to another block in a rewrite operation. An improved pre-emptive rewrite scheme prevents a worst-case situation where multiple rewrites to occur at once when they happened to be full at the same time. Particularly, the scheduling of the pre-emptive rewrites for control data is based on a number of considerations including the time required for each control block rewrite and the time available for control block rewrites based on the configuration of the update blocks for storing host data, the time required in the foreground host operation and the host write latency.
摘要翻译：在具有块管理系统的非易失性存储器中，写入块的数据包括主机写入数据以及用于管理块的系统控制数据。当块已满或不再接受数据时，在重写操作中将其上的数据的有效版本重定位到另一个块之后，它将被关闭。改进的优先重写方案可以防止在同时发生多次重写时立即发生多次重写的最坏情况。特别地，用于控制数据的优先重写的调度基于多个考虑因素，包括基于用于存储主机数据的更新块的配置，每个控制块重写所需的时间和可用于控制块重写的时间，前台主机操作所需的时间和主机写入延迟。

摘要： A flash memory system, including a flash memory device and a controller, and having improved efficiency error correction coding (ECC), is disclosed. Each page in the flash memory device has the capacity to store multiple sectors' worth of data. However, partial page programming (i.e., followed by a later write to fill the page) is prohibited for reliability reasons. A scratchpad block within the flash memory device is designed, and stores both user data and control data. ECC efficiency is improved by encoding the ECC, or parity, bits over the entire data block corresponding to the user and control data in the page. Retrieval of a particular sector of data requires reading and decoding of the entire page. Especially for codes such as Reed-Solomon and BCH codes, the larger data block including multiple sectors' data improves the error correction capability, and thus enables either fewer redundant memory cells in each page or improved error correction.
