摘要： Systems and methods are provided for obtaining and using nonvolatile memory ("NVM") health information. Health information can include a variety of information associated with the performance and reliability of portions of an NVM device, such as the number of errors detected in a portion of NVM or the amount of time required to read from or program a portion of nonvolatile memory. During operation, address specific health information may be stored passively on a host device and provided as part of a command to a memory controller. The memory controller may extract the health information from the command and use the information to execute access requests. After an access request is completed, the memory controller can update the health information and transmit the information back to the host device.

摘要： Memory mapping techniques for non-volatile memory are disclosed where logical sectors are mapped into physical pages using data structures in volatile and non-volatile memory. In some implementations, a first lookup table in non-volatile memory maps logical sectors directly into physical pages. A second lookup table in volatile memory holds the location of the first lookup table in non-volatile memory. An index cache tree in volatile memory holds the physical addresses of the most recently written or accessed logical sectors in a compressed format.

摘要： Systems and methods are disclosed for providing a weave sequence counter ("WSC") for non-volatile memory ("NVM") systems. The WSC can identify the sequence in which each page of the NVM is programmed. The "weave" aspect can refer to the fact that multiple blocks can be open for programming at once, thus allowing the pages of these blocks to be programmed in a "woven" manner. Systems and methods are also disclosed for providing a host weave sequence counter ("HWSC"). Each time new data is initially programmed to the NVM, this data can be associated with a particular HWSC. The HWSC associated with the data may not change, even when the data is moved to a new page (e.g., for wear leveling purposes and the like). The WSC and HWSC may aid in, for example, performing rollback, building logical -to-physical mappings, determining static-versus-dynamic page statuses, and performing maintenance operations (e.g., wear leveling).
摘要翻译：公开了用于为非易失性存储器（“NVM”）系统提供编织序列计数器（“WSC”）的系统和方法。 WSC可以识别NVM的每个页面被编程的顺序。 “编织”方面可以指多个块可以一次打开以进行编程，从而允许以“编织”的方式对这些块的页面进行编程。还公开了用于提供主机编织序列计数器（“HWSC”）的系统和方法。每当新数据最初被编程到NVM时，该数据可以与特定的HWSC相关联。即使将数据移动到新页面（例如，用于磨损均衡目的等），与数据相关联的HWSC也可能不会改变。 WSC和HWSC可以帮助例如执行回滚，构建逻辑到物理映射，确定静态到动态页面状态以及执行维护操作（例如，磨损均衡）。

摘要： In a memory system, a host controller is coupled to a non-volatile memory (NVM) package (e.g., NAND device). The host controller sends a read command to the NVM package requesting a low latency read operation. Responsive to the read command, a controller in the NVM package retrieves the data and sends the data to an ECC engine for correcting. Following the read command, the host controller sends a read status request command to the controller in the NVM package. Responsive to the read status request, the controller sends a status report to the host controller indicating that some or all of the data is available for transfer to the host controller. Responsive to the report, the host controller transfers the data. An underrun status can be determined to indicate that uncorrected data had been transferred to the host controller.

摘要： The disclosed architecture uses address mapping to map a block address on a host interface to an internal block address of a non-volatile memory (NVM) device. The block address is mapped to an internal chip select for selecting a Concurrently Addressable Unit (CAU) identified by the block address. The disclosed architecture supports generic NVM commands for read, write, erase and get status operations. The architecture also supports an extended command set for supporting read and write operations that leverage a multiple CAU architecture.
