摘要： A re-programmable non-volatile memory system, such as a flash EEPROM system, having its memory cells grouped into blocks of cells that are simultaneously erasable is operated to perform memory system housekeeping operations in the foreground during execution of a host command, wherein the housekeeping operations are unrelated to execution of the host command. Both one or more such housekeeping operations and execution of the host command are performed within a time budget established for executing that particular command. One such command is to write data being received to the memory. One such housekeeping operation is to level out the wear of the individual blocks that accumulates through repetitive erasing and re-programming.

摘要： A method and system for cache management in a storage device is disclosed. A portion of unused memory in the storage device is used for temporary data cache so that two levels of cache may be used (such as a permanent data cache and a temporary data cache). The storage device may manage the temporary data cache in order to maintain clean entries in the temporary data cache. In this way, the storage area associated with the temporary data cache may be immediately reclaimed and retasked for a different purpose without the need for extraneous copy operations.

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. The data are sorted either for storing into different storage portions, such as SLC and MLC, or into different operating streams, depending on their temperatures. This allows data of similar temperature to be dealt with in a manner appropriate for its temperature in order to minimize rewrites. Examples of a unit of data include a logical group and a block.

摘要： A memory device cooperating with a memory controller scrambles each unit of data using a selected scrambling key before storing it in an array of nonvolatile memory cells. This helps to reduce program disturbs, user read disturbs, and floating gate to floating gate coupling that result from repeated and long term storage of specific data patterns. For a given page of data having a logical address and for storing at a physical address, the key is selected from a finite sequence thereof as a function of both the logical address and the physical address. In a block management scheme the memory array is organized into erase blocks, the physical address is the relative page number in each block. When logical address are grouped into logical groups and manipulated as a group and each group is storable into a sub-block, the physical address is the relative page number in the sub-block.
摘要翻译：与存储器控制器协作的存储器件在将其存储在非易失性存储器单元阵列之前，使用所选择的加密密钥对每个数据单元进行加扰。这有助于减少由特定数据模式的重复和长期存储引起的程序干扰，用户读取干扰和浮动栅极到浮动栅极耦合。对于具有逻辑地址并用于存储在物理地址的给定页面的数据，从作为逻辑地址和物理地址的函数的有限序列中选择密钥。在块管理方案中，存储器阵列被组织成擦除块，物理地址是每个块中的相对页号。当逻辑地址分组为逻辑组并作为组操作并且每个组可存储到子块中时，物理地址是子块中的相对页号。

摘要： A method of writing data to a non-volatile memory with minimum units of erase of a block, a page being a unit of programming of a block, may read a page of stored data addressable in a first increment of address from the memory into a page buffer, the page of stored data comprising an allocated data space addressable in a second increment of address, pointed to by an address pointer, and comprising obsolete data. The first increment of address is greater than the second increment of address. A portion of stored data in the page buffer may be updated with the data to form an updated page of data. Storage space for the updated page of data may be allocated. The updated page of data may be written to the allocated storage space. The address pointer may be updated with a location of the allocated storage space.

摘要： In a nonvolatile memory with block management system, critical data such as control data for the block management system is maintained in duplicates. Various methods are described for robustly writing and reading two copies of critical data in multi-state memory. In another aspect of the invention, a preemptive garbage collection on memory block containing control data avoids an undesirable situation where a large number of such memory blocks need be garbage collected at the same time.

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 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.
