    Abstract: Systems and processes may be used to retrieve metadata from a nonvolatile memory of a portable device and transmit the retrieved metadata to an external host. Metadata may be analyzed using the external host and/or at least a portion of the metadata may be modified based on the analysis. Modified metadata may be transmitted from the external host to a memory controller of the host.

    Abstract: Systems and processes may use a host and an external host. The host may be a portable device that includes a memory, a memory controller, and a communication interface for communication with the external host. The portable device may receive a command signal from the external host and initiate a predetermined amount of wear leveling in response to the command signal.

    Abstract: A partial voltage level read is made on memory cells of a solid state memory device during a voltage settling time after the memory cells are charged (e.g., by a pulse from a charge pump). Digital values representing partial voltage levels are checked for errors (e.g., by an error correction code (ECC) engine). If the values can be corrected, then the values are released for host access. If the values cannot be corrected, then a full voltage read is performed on the memory cells after the voltage levels have substantially settled. Digital values corresponding to the full voltage reads can be released for host access. The use of partial voltage reads results in faster read of solid state memory devices.

    Abstract translation: 在存储器单元被充电之后的电压建立时间（例如，通过来自电荷泵的脉冲）期间，在固态存储器件的存储器单元上进行部分电压电平读取。 检查表示部分电压电平的数字值是否存在错误（例如，通过纠错码（ECC）引擎）。 如果可以更正这些值，则释放主机访问的值。 如果这些值无法校正，则在电压电平基本稳定后，对存储单元执行全电压读取。 可以释放与全电压读数相对应的数字值，以进行主机访问。 使用部分电压读数可以更快地读取固态存储器件。
