    • A data storage device includes a controller coupled to a non-volatile memory having a three-dimensional (3D) configuration. The non-volatile memory includes a group of storage elements. Each storage element is configured to store multiple data bits. Data is sent from the controller to the non-volatile memory and first bits corresponding to a first portion of the data are stored into the group of storage elements during a first write stage. Each storage element of the group of storage elements stores at least one bit of the first bits upon completion of the first write stage. Second bits corresponding to a second portion of the data are sent to a second memory without sending the first bits to the second memory. The second bits are retrieved from the second memory and at least the second bits are stored into the group of storage elements during a second write stage.
    • 数据存储设备包括耦合到具有三维(3D)配置的非易失性存储器的控制器。 非易失性存储器包括一组存储元件。 每个存储元件被配置为存储多个数据位。 数据从控制器发送到非易失性存储器,并且对应于数据的第一部分的第一位在第一写入阶段被存储到存储元件组中。 存储元件组中的每个存储元件在第一写入阶段完成时存储第一位的至少一个位。 对应于数据的第二部分的第二位被发送到第二存储器,而不将第一位发送到第二存储器。 从第二存储器检索第二位,并且在第二写入阶段期间至少将第二位存储到存储元件组中。
