A system on chip (SoC) adjusts power of a memory through a handshake. The SoC includes a memory controller and a power manager. The memory controller is configured to control a memory. The power manager is configured to manage a supply power level of the memory. The memory controller is configured to output, to the power manager, a memory access level indicating a frequency of accesses to the memory. The power manager is configured to adjust the supply power level of the memory according to the memory access level.

System on chip controlling memory power using handshake process and operating method thereof

Location information is received from a terrestrial location indicator device. The location information is based on location of the terrestrial location indicator device. Location information is also determined from a GPS satellite signal. The location of a device relative to an object in a map is determined based on the location information from the terrestrial location indicator device and the location information from the GPS satellite signal. The location information from the terrestrial location indicator device may be used to distinguish the device location relative to at least two adjacent objects, such as roads, in a map.
