摘要： In a nonvolatile memory array, blocks that contain only obsolete data are modified by adding charge to their cells, increasing the charge level from the programmed charge levels that represented obsolete data to elevated charge levels. The increase in overall charge in such blocks lessens the tendency of such blocks to impact data retention in neighboring blocks.

摘要： A non-volatile memory system includes a memory section having a non-volatile cache portion storing data in a binary format, a primary user data storage section that stores user data in multi-state format, and an update memory area where the memory system stores data updating user data previously stored in the primary user data. The memory system allows a maximum number of blocks for use in the update memory area. When the memory system receives updated data corresponding to user data already written into the primary user data storage section, it determines whether a block of memory is available in the update memory area. In response to determining that a block of memory is not available in the update memory area, the system determines a block of the update memory to remove from the update memory; copies the data content of the determined update block into the cache portion of the memory section; and subsequently writes the updated data into the update memory.

摘要： A non-volatile memory organized into flash erasable blocks sorts units of data according to a temperature assigned to each unit of data, where a higher temperature indicates a higher probability that the unit of data will suffer subsequent rewrites due to garbage collection operations. The units of data either come from a host write or from a relocation operation. Among the units more likely to suffer subsequent rewrites, a smaller subset of data super-hot is determined. These super-hot data are then maintained in a dedicated portion of the memory, such as a resident binary zone in a memory system with both binary and MLC portions.

摘要： A method and system pre-emptively perform garbage collection operations of a forced amount on update blocks in a memory device. The amount of garbage collection needed by a certain data write is monitored and adjusted to match the forced amount if necessary. Update blocks may be selected on the basis of their recent usage or the amount of garbage collection required. Another method and system may store control information about update blocks in a temporary storage area so that a greater number of update blocks are utilized. The sequential write performance measured by the Speed Class test may be optimized by using this method and system.

摘要： A method and system for performing garbage collection operations on update blocks in a memory device using volatile memory is disclosed. When performing a garbage collection operation, a first part of the data related to the garbage collection operation is written to a volatile memory in the memory device, and a second part of the data related to the garbage collection operation is written to a non-volatile memory in the memory device. The first part of the data that is written to the volatile memory (such as a random access memory) may comprise control information (such as mapping information of the logical addressable unit to a physical metablock). The second part of the data related to the garbage collection that is written to the non-volatile memory (such as a flash memory) may comprise the consolidated data in the update block.

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。
