Semiconductor device and semiconductor system for performing an initialization operation

摘要

Semiconductor systems are provided. A semiconductor system may include a first semiconductor device and a second semiconductor device. The first semiconductor device may output a command and a power supply voltage. The second semiconductor device may generate pulses of a reset signal for an initialization operation and pulses of an auto-refresh signal for an auto-refresh operation in response to a first reset command generated in response to the command after the power supply voltage reaches a target voltage level. The second semiconductor device may generate the pulses of the reset signal in response to a second reset command generated in response to the command.
