Semiconductor device including a high voltage generation circuit and method of generating a high voltage
摘要：
A semiconductor memory device includes a first pump clock generator configured to generate a first pump clock signal based on a power supply voltage. The device also includes a first charge pump configured to generate a first pump output voltage in response to the first pump clock signal. The device also includes a second pump clock generator configured to generate a second pump clock signal based on the first pump output voltage. The device also includes a second charge pump configured to generate a second pump output voltage in response to the second pump clock signal. The device also includes a switching unit configured to selectively connect the first charge pump to the second charge pump.
