| 主权项 | 1. A buffer circuit comprising: an amplification unit suitable for sensing and amplifying an input signal and a reference voltage; a buffer enable unit suitable for enabling the amplification unit based on a buffer enable signal; and a buffer enable signal generation unit suitable for generating the buffer enable signal based on a first or second operation control signal, selected according to a high voltage detection signal generated by detecting a power supply voltage, wherein the high voltage detection signal is activated when the power supply voltage is greater than or equal to a predetermined voltage, and deactivated when the power supply voltage is less than the predetermined voltage. | ||
