    Abstract: In a nonvolatile memory system that includes a block-erasable memory array, records are individually maintained for certain classifications of blocks. One or more lists may be maintained for the blocks, an individual list ordered according to a descriptor value. Such ordered lists allow rapid identification of a block by descriptor value.

    Abstract: A multi-layer memory and method for operation is disclosed. The memory includes multiple layers, where each layer includes flash memory cells having a greater bit per cell capacity than the prior layer and each layer may include a plurality of partitions having blocks exclusively associated with a particular data type. The method may include directing host data directly into a particular partition of a particular layer of the multi-layer memory upon receipt depending on a type of the data. The method may also include copying data within the same partition in a respective layer in a data relocation operation to generate more free blocks of memory so that data preferably stays within each layer and in the same partition, as well as transferring data from one layer to the next higher bit per cell layer within a same partition when layer transfer criteria are met.

    Abstract: A multi-later memory and method for operation is disclosed. The memory includes three or more layers, where each layer is made up of flash memory cells having a greater bit per cell storage capacity than then prior layer. The method may include the steps of directing host data directly into a first or second layer of the multi-layer memory upon receipt depending on a condition of the data. The method may also include copying data within a respective layer in a data relocation operation to generate more free blocks of memory so that data preferably stays within each layer, as well as transferring data from one layer to the next higher bit per cell layer when layer transfer criteria are met.

    Abstract: A multi-layer memory and method for operation is disclosed. The memory includes an interface, at least one flash memory die having a plurality of layers and a controller. The controller is configured to select an appropriate one of a predetermined number of program cycles for programming a fixed amount of host data, and for carrying out maintenance operations in one or more of the layers sufficient to permit a next host data write operation. The controller calculates an interleave ratio of maintenance operations to host data programming operations in each of the layers used in the determined programming cycle so that creation of free space is interspersed with host data writes in a steady manner during execution of the determined programming cycle.

    Abstract: A system and method for managing program cycles in a multi-layer memory is disclosed. The method includes a controller receiving a request to program data from a host and, in advance of programming data associated with the request, determining a program cycle for programming the data associated with the request and an amount of data already programmed in the plurality of memory layers necessary to be programmed in maintenance operations to provide free memory capacity for a subsequent request to program data from the host. The controller programs the data associated with the request, and the amount of data already programmed to be programmed in maintenance operations, in predetermined programming units according to the determined program cycle.

    Abstract: 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.

    Abstract translation: 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。
