摘要： A method and system maintains an address table for mapping logical groups to physical addresses in a memory device. The method includes receiving a request to set an entry in the address table and selecting and flushing entries in an address table cache depending on the existence of the entry in the cache and whether the cache meets a flushing threshold criteria. The flushed entries include less than the maximum capacity of the address table cache. The flushing threshold criteria includes whether the address table cache is full or if a page exceeds a threshold of changed entries. The address table and/or the address table cache may be stored in a non- volatile memory and/or a random access memory. Improved performance may result using this method and system due to the reduced number of write operations and time needed to partially flush the address table cache to the address table.

摘要： A method of managing page-based data storage media such as flash media, a system that uses the method, and a computer-readable storage medium bearing code for implementing the method. For each page, a corresponding risk zone, of other pages whose data are put at risk of corruption if writing to the page is interrupted, is identified. When a page is selected for writing new data, the written pages in its risk zone are copied to a log. As necessary, corrupt data are replaced with corresponding data from the log.

摘要： A method for data storage includes storing data in a memory including multiple analog memory cells arranged in blocks. A first subset of the blocks is defined for storing first data with a first storage density, and a second subset of the blocks is defined for storing second data with a second storage density, larger than the first storage density. In each of the first and second subsets, one or more blocks are allocated to serve as spare blocks and blocks that become faulty are replaced with the spare blocks. Upon detecting that a number of the spare blocks in the second subset has decreased below a predefined threshold, the data is copied from at least one block in the second subset to the first subset, and the at least one block is added to the spare blocks of the second subset.

摘要： A method for operating a memory includes receiving memory access commands associated with respective target logical addresses, for execution in a memory. The target logical addresses are translated into respective intermediate logical addresses, in accordance with a first mapping having a first granularity of a first data unit size. The intermediate logical addresses are translated into respective physical storage locations in the memory, in accordance with a second mapping having a second granularity of a second data unit size, larger than the first data unit size. The memory access commands are executed in the memory in accordance with the respective physical storage locations.

摘要： A portion of a nonvolatile memory is partitioned from a main multi-level memory array to operate as a cache. The cache memory is configured to store at less capacity per memory cell and finer granularity of write units compared to the main memory. In a block-oriented memory architecture, the cache has multiple functions, not merely to improve access speed, but is an integral part of a sequential update block system. Decisions to write data to the cache memory or directly to the main memory or decisions to archive data from the cache memory to the main memory depend on the attributes and characteristics of the data to be written, the state of the blocks in the main memory portion and the state of the blocks in the cache portion. The cache memory has a capacity dynamically increased by allocation of blocks from the main memory in response to a demand to increase the capacity. Preferably, a block with an endurance count higher than average is allocated. The logical addresses of data are partitioned into zones to limit the size of the indices for the cache.
摘要翻译：将非易失性存储器的一部分从主多层存储器阵列分区以作为高速缓存进行操作。缓存存储器被配置为以比每个存储器单元更少的容量存储和与主存储器相比写入单元的更细粒度。在面向块的存储器架构中，缓存具有多个功能，而不仅仅是提高访问速度，而是顺序更新块系统的组成部分。将数据写入高速缓冲存储器或直接写入主存储器的决定或将数据从高速缓冲存储器归档到主存储器的决定取决于要写入的数据的属性和特性，主存储器部分中的块的状态以及高速缓存部分中的块的状态。响应于增加容量的需求，高速缓冲存储器具有通过从主存储器分配块而动态增加的容量。优选地，分配耐力计数高于平均值的块。数据的逻辑地址被划分为区域以限制高速缓存的索引的大小。
