    Abstract: A storage device includes a nonvolatile memory and a memory controller. The memory controller is configured to receive a first program request from an external host device and program first memory cells of a memory block according to the first program request. The memory controller is further configured to program second memory cells of the memory block without a request of the external host device if a second program request is not received from the external host device for a critical time.

    Abstract translation: 存储装置包括非易失性存储器和存储器控制器。 存储器控制器被配置为从外部主机设备接收第一程序请求，并根据第一程序请求对存储块的第一存储器单元进行编程。 如果在关键时间没有从外部主机设备接收到第二程序请求，则存储器控制器还被配置为对存储块的第二存储器单元进行编程，而不需要外部主机设备的请求。

    Abstract: A solid state drive includes: a plurality of non-volatile memories, each of the non-volatile memories connected to a channel, the channel connected to at least one way connected to a die; a host interface which receives stream data and stream information from a host; and a resource allocator which allocates the stream data to super blocks of the plurality of non-volatile memories on the basis of the stream information. A super block includes a unit super block, and the unit super block includes a block of a first die corresponding to a first channel and connected to a plurality of the ways connected to the first channel. The stream data may include stream groups, and the stream information may include the number of streams included in a stream group.
