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.
摘要翻译：公开了用于非易失性存储器的存储器映射技术，其中使用易失性和非易失性存储器中的数据结构将逻辑扇区映射到物理页面。在一些实现中，非易失性存储器中的第一查找表将逻辑扇区直接映射到物理页面中。易失性存储器中的第二查找表将第一查找表的位置保存在非易失性存储器中。易失性存储器中的索引缓存树以压缩格式保存最近写入或访问的逻辑扇区的物理地址。

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.
摘要翻译：在存储器系统中，主机控制器耦合到非易失性存储器（NVM）封装（例如，NAND器件）。主机控制器向NVM包发送读取命令，请求低延迟读取操作。响应于读取命令，NVM包中的控制器检索数据并将数据发送到ECC引擎进行校正。在读取命令之后，主机控制器向NVM包中的控制器发送读状态请求命令。响应于读取状态请求，控制器向主机控制器发送状态报告，指示部分或全部数据可用于传送到主机控制器。响应报告，主机控制器传输数据。可以确定欠运行状态以指示未校正的数据已被传送到主机控制器。
