Document Type and Number:
Japanese Patent JP2867255
Kind Code:
B2
Abstract:
Provided is a sensing amplifier driving/controlling circuit for supplying pull-up/down voltage to a sensing amplifier of a semiconductor memory device, including: a first switching device for connecting internal voltage to the first driving line which in turn applies high voltage to the sensing amplifier; a second switching device for connecting an external voltage to the first driving line which in turn applies high voltage to the sensing amplifier; a third switching device for connecting ground voltage to a second driving line which in turn applies ground voltage to the sensing amplifier; a comparator having an inverse input terminal which is connected to the first driving line and a non-inverse input terminal which receives a reference voltage and thus the comparator is enabled when receiving first and second control signals; an inverter for inverting the first control signal and applying the inverse signal to the control input terminal of the first switching device; and a NAND gate for receiving the outputs of the comparator and the first control signal with its input terminals and performing a NAND operation.
