Patent ID: 7924595

Claim:
A high-density semiconductor device comprising: a first bank group and a second bank group on a core area; a first input/output line coupled to the first bank group, to transmit data; a second input/output line coupled to the second bank group, to transmit data; a data pad for inputting and outputting data on a peri area; a third input/output line coupled to the data pad, to transmit data; a first repeater comprising a first delay unit configured to delay a first read enable signal enabled by a read command for the first bank group by a predetermined period of time, a first buffer configured to buffer the first input/output line signal, a first transfer element configured to transfer an output signal of the first buffer as a first pull-up signal in response to the output signal of the first delay unit, and a second transfer element configured to transfer an output signal of the first buffer as a first pull-down signal in response to the output signal of the first delay unit, a first pull-up element configured to receive the first pull-up signal and pull-up the third input/output line, and a first pull-down element configured to receive the first pull-down signal and pull-down the third input/output line, wherein the first repeater is coupled between the first input/output line and the third input/output line.
