    Abstract: A system includes: a nonvolatile memory; a memory controller configured to control the nonvolatile memory, the memory controller including a first buffer memory for temporarily storing write data to be written to the nonvolatile memory; and a second buffer memory having a lower operational speed and a higher memory capacity than the first buffer memory. The memory controller is configured to transmit the write data from the first buffer memory to the second buffer memory and to the nonvolatile memory, and to release an operational state of the first buffer memory after transmitting the write data from the first buffer memory to the second buffer memory and to the nonvolatile memory. Writing additional write data to the first buffer memory is prohibited prior to the release of the operational state of the first buffer memory, and is permitted after the release of the operational state of the first buffer memory.

    Abstract: A storage device includes nonvolatile memories and a controller. The controller previously manages a correspondence relationship between physical addresses indicating the memory regions and stream identifiers, before first write data is received by the controller. The controller controls the nonvolatile memories such that the first write data is stored in a first memory region of a physical address which is managed corresponding to a first stream identifier of the first write data in the correspondence relationship. The first write data is transferred to the nonvolatile memories based on the correspondence relationship, regardless of whether second write data having a second stream identifier is received by the controller.

    Abstract: A display driving circuit includes a gamma generator configured to output, to nodes, gamma voltages having different voltage levels, and a selector configured to select one of the nodes to which the gamma voltages are output, and output a voltage of the selected one of the nodes. The display driving circuit further includes a voltage regulator configured to selectively input a first current to the selected one of the nodes and output a second current from the selected one of the nodes, based on the voltage of the selected one of the nodes, to adjust a voltage level of the voltage of the selected one of the nodes to a voltage level of a respective one of the gamma voltages that is output to the selected one of the nodes.

    Abstract: A nonvolatile memory system includes first and second nonvolatile memory devices and a memory controller configured to control the first and second nonvolatile memory devices through one channel. During a program operation, the memory controller transmits first signals, for setting first page data up in the first nonvolatile memory device, to the first nonvolatile memory device through the channel. While the first nonvolatile memory device sets up the first page data in response to the first signals, the memory controller transmits second signals, for setting second page data up in the second nonvolatile memory device, to the second nonvolatile memory device.
