Abstract
A data input device of a semiconductor memory apparatus includes input means configured to input data; precharge means configured to supply a precharge voltage for converting inputted data to a differential signal; enable means configured to enable the input means and the precharge means to operate; and control means configured to control a current amount of the enable means in a standby mode.
Claims20
A data input device of a semiconductor memory apparatus, comprising:
- input means configured to input data;
- precharge means configured to supply a precharge voltage for converting inputted data to a differential signal;
- enable means configured to enable the input means and the precharge means to operate;
- and
- control means configured to control a current amount of the enable means in a standby mode.
A method for controlling a data input device of a semiconductor memory apparatus, comprising:
- enabling the data input device so that data can be inputted;
- controlling a current amount of the enabled data input device in a standby mode;
- inputting data to the data input device;
- and
- converting inputted data to a differential signal and outputting the differential signal.
A data input device of a semiconductor memory apparatus, comprising:
- a differential amplifier for comparing input to a reference voltage and outputting a differential signal based on the comparison;
- and
- a control circuit for adjusting a current driving capacity of the differential amplifier by turning on a first current path connected to the differential amplifier in response to a first enable signal and turning off a second current path connected to the differential amplifier in response to a second enable signal in a standby mode, wherein, during a time that external command signals toggle back and forth between a status of being all high signals or a status of being all low signals repeatedly, the second enable signal is controlled to be maintained at a low state signal.
