摘要： In a nonvolatile memory with block management system that supports update blocks with non-sequential logical units, an index of the logical units in a non-sequential update block is buffered in RAM and stored periodically into the nonvolatile memory. In one embodiment, the index is stored in a block dedicated for storing indices. In another embodiment, the index is stored in the update block itself. In yet another embodiment, the index is stored in the header of each logical unit. In another aspect, the logical units written after the last index update but before the next have their indexing information stored in the header of each logical unit. In this way, after a power outage, the location of recently written logical units can be determined without having to perform a scanning during initialization. In yet another aspect, a block is managed as partially sequential and partially non-sequential, directed to more than one logical subgroup.
摘要翻译：在具有支持具有非顺序逻辑单元的更新块的块管理系统的非易失性存储器中，非顺序更新块中的逻辑单元的索引被缓冲在RAM中并被周期性地存储到非易失性存储器中。在一个实施例中，索引被存储在专用于存储索引的块中。在另一个实施例中，索引被存储在更新块本身中。在另一个实施例中，索引被存储在每个逻辑单元的标题中。在另一方面，在最后一个索引更新之后但在下一个之前写入的逻辑单元将其索引信息存储在每个逻辑单元的标题中。以这种方式，在断电之后，可以确定最近写入的逻辑单元的位置，而不必在初始化期间执行扫描。在另一方面，块被部署顺序地且部分地非顺序地管理，定向到多于一个的逻辑子组。

摘要： A memory system (10) having a solid state memory (6) comprising non-volatile individually addressable memory sectors (1) arranged in erasable blocks, and a controller (8) for writing to reading from the sectors, and for sorting the blocks into “erased” and “not erased” blocks. The controller performs logical to physical address translation, and includes a Write Pointer (WP) for pointing to the physical sector address to which data is to be written from a host processor. A Sector Allocation Table (SAT) of logical adrresses with respective physical addresses is stored in the memory, and the controller updates the SAT less frequently than sectors are written to with data from the host processor. The memory may be in a single chip, or in a plurality of chips. A novel system for arranging data in the individual sectors (1) is also claimed.

摘要： The present invention presents a hybrid non-volatile system that uses non-volatile memories based on two or more different non-volatile memory technologies in order to exploit the relative advantages of each these technology with respect to the others. In an exemplary embodiment, the memory system includes a controller and a flash memory, where the controller has a non-volatile RAM based on an alternate technology such as FeRAM. The flash memory is used for the storage of user data and the non-volatile RAM in the controller is used for system control data used by the control to manage the storage of host data in the flash memory. The use of an alternate non-volatile memory technology in the controller allows for a non-volatile copy of the most recent control data to be accessed more quickly as it can be updated on a bit by bit basis. In another exemplary embodiment, the alternate non-volatile memory is used as a cache where data can safely be staged prior to its being written to the to the memory or read back to the host.

摘要： A non-volatile memory system is organized in physical groups of physical memory locations. Each physical group (metablock) is erasable as a unit and can be used to store a logical group of data. A memory management system allows for update of a logical group of data by allocating a metablock dedicated to recording the update data of the logical group. The update metablock records update data in the order received and has no restriction on whether the recording is in the correct logical order as originally stored (sequential) or not (chaotic). Eventually the update metablock is closed to further recording. One of several processes will take place, but will ultimately end up with a fully filled metablock in the correct order which replaces the original metablock. In the chaotic case, directory data is maintained in the non-volatile memory in a manner that is conducive to frequent updates. The system supports multiple logical groups being updated concurrently.

摘要： A multi-later memory and method for operation is disclosed. The memory includes at least one flash memory die having multiple layers and a controller configured to execute block reclaim operations in a layer of the flash memory die until a net gain of at least one additional free block has been made in the layer. The method may include relocating data from reclaim blocks to relocation blocks within the same layer, or within a same partition in the same layer until a net gain of one free block has been achieved and an integer number of relocation blocks has been filled with relocated data. The method may also include moving data from reclaim blocks in a first layer into destination blocks in a second layer until a net gain of at least one free block has been achieved in the first layer.

摘要： A multi-layer memory and method for performing background maintenance operations are disclosed. The memory includes a plurality of flash memory die having multiple layers, where each layer is made up of flash memory cells having a greater bit per cell storage capacity than then prior layer and each layer may have a plurality of partitions for different data types. A controller managing the flash memory die is configured to identify an idle die and determine if a layer in the die satisfies a background maintenance criterion. Upon identifying a layer satisfying the background maintenance criterion, the valid data from reclaim blocks in the layer is relocated into a relocation block in the same layer until the relocation block is filled and the background maintenance cycle ends.
