A user device is provided. The device includes a main power supply, and an auxiliary power supply. The main power supply provides a main power. The auxiliary power supply cuts off the main power according to a power level of the main power supply and provides an auxiliary power upon Sudden Power-Off (SPO).

Auxiliary power supply and user device including the same

An apparatus includes a multiprocessor including a plurality of processors including respective memories. Each of the memories has a dedicated storage location for multicast messages. At least one bus is coupled in common to the plurality of processors. The apparatus further includes an IPC unit coupled to the at least one bus and configured to retrieve multicast messages from the dedicated storage locations via the at least one bus and to selectively route the retrieved multicast messages among the plurality of memories.

Multi-processor apparatus using dedicated buffers for multicast communications

A semiconductor device with flash memory includes; a log type determining unit configured to select log type from among a plurality of log types with respect to a log block storing program data requested to be programmed in the flash memory and generate a control signal indicating information indicating the selected log type, and a plurality of log units configured to store program data in the log block having a corresponding log type in response to the control signal, wherein the log type determining unit converts a first type log block formed by a first log type and included in a first type log unit from among the plurality of log units into second type log block formed by a second log type and converts the log block included in a second type log unit from among the plurality of log units into the first type log blocks, the first log type being different from the second log type.
