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

An application processor includes a system bus, a host processor, a voice trigger system and an audio subsystem that are electrically connected to the system bus. The voice trigger system performs a voice trigger operation and issues a trigger event based on a trigger input signal that is provided through a trigger interface. The audio subsystem includes an audio interface and processes audio streams through the audio interface. The voice trigger system is disposed in an always-powered domain where power is supplied in both of an active mode and a standby mode. The host processor and the audio subsystem are disposed in a power-save domain where power is blocked in the standby mode. The host processor launches into the active mode when the voice trigger system issues the trigger event.
