摘要： A method includes, in a data storage device including a non-volatile memory, receiving, from a host device, a read command to read data from the non-volatile memory. The host device is coupled to the data storage device and includes a memory having a unified memory (UM) area. The method also includes, responsive to the read command, sending a UM read command to the host device. The UM read command instructs the host device to read the data from a location of the UM area.

摘要： A data storage device includes a write protection data structure that includes a first set of entries corresponding to a first set of ranges of memory addresses. A first indication stored in an entry, in the first set of entries, corresponds to an absence of write-protected data between a lowest address of the range of addresses corresponding to the entry and a highest address of a memory. A second indication stored in the entry corresponds to write-protected data within the range of addresses. The data storage device also includes a write protection map that includes a second set of entries corresponding to a second set of ranges of the memory addresses. The device is configured to locate, in the write protection data structure, an entry corresponding to a range of memory addresses.
摘要翻译：数据存储设备包括写保护数据结构，其包括对应于第一组存储器地址范围的第一组条目。在第一组条目中存储在条目中的第一指示对应于在对应于条目的地址范围的最低地址和存储器的最高地址之间不存在写保护数据。存储在条目中的第二指示对应于地址范围内的写保护数据。数据存储设备还包括写保护映射，其包括与存储器地址的第二组范围对应的第二组条目。该设备被配置为在写保护数据结构中定位与存储器地址范围相对应的条目。

摘要： A data storage device may be configured to direct access to at least a portion of a host memory of a host device. For example, the data storage device may store data at the host memory, such as data predicted to be subject to a read request from the host device. When the data storage device receives a read request from the host device to read the data, the data storage device may send an indication to the host device to enable the host device to read the data directly from the host memory.
摘要翻译：数据存储设备可以被配置为直接访问主机设备的主机存储器的至少一部分。例如，数据存储设备可以在主机存储器处存储数据，例如预测要受主机设备的读请求的数据。当数据存储设备从主机设备接收到读取数据的读取请求时，数据存储设备可以向主机设备发送指示，使得主机设备能够从主机存储器直接读取数据。

摘要： A method includes, in response to a first write command corresponding to first data and a first context which is identifiable with a first identifier and to a second write command corresponding to second data and a second context identifiable with a second identifier, determining whether the first identifier of the first context matches the second identifier of the second context. The method also includes, if the first identifier of the first context is determined to match the second identifier of the second context, forming a compression group of data including the first data and the second data, and generating compressed data corresponding to the compression group of data.
摘要翻译：一种方法包括：响应于对应于第一数据的第一写入命令和可用第一标识符识别的第一上下文以及与第二数据相对应的第二写入命令和可识别的第二标识符的第二上下文，确定第一第一上下文的标识符与第二上下文的第二标识符匹配。该方法还包括：如果确定第一上下文的第一标识符与第二上下文的第二标识符匹配，则形成包括第一数据和第二数据的压缩数据组，并且生成与压缩组对应的压缩数据数据。
