Patent ID: 7339397

Claim:
A data output apparatus in a global input and output (GIO) line, the apparatus comprising: a read driver driven responsive to an input of read data for inverting and amplifying the data to output inverted and amplified data onto the GIO line; a GIO termination unit including a low current sink circuit for rising a voltage level on the GIO line by a first preset level, prior to driving logic low read data onto the GIO line by the read driver, wherein the low current sink circuit has a first switch being on/off in response to a first termination signal and a first MOS diode connected transistor serially connected between a supply voltage and the GIO line; and a receiver driven responsive to the read data transmitted through the GIO line for inverting and amplifying the read data to provide inverted and amplified data, wherein a first current sink path is formed by sequentially passing through the supply voltage, the low current sink circuit, the GIO line, the read driver, and a ground voltage when the logic low read data is being driven onto the GIO line in response to the first termination signal.
