An electronic device includes a light source, a light sensor, and a controller that senses an amount of a coarse ambient light by turning off the light source and performing sensing in a coarse mode by using the light sensor and senses an amount of a fine ambient light by performing sensing in a fine mode by using the light sensor. The controller senses an amount of a target light by turning on the light source and performing sensing by using the light sensor while the light source emits a light, and outputs information based on the amount of the coarse ambient light, the amount of the fine ambient light, and the amount of the target light.

Electronic device and operating method of electronic device

A memory controller of inventive concepts may include an active regulator configured to operate in an active mode and be inactive in a sleep mode, an active logic configured to receive a drive voltage, a power gating switch configured to connect the active regulator to the active logic after a transient state of the active mode, the transient state being an initial time period of the active mode, and a charging circuit configured to charge the active logic during the transient state.
