US 2019/0295612 A1 · DATA TRANSFER DEVICE AND SEMICONDUCTOR DEVICE INCLUDING THE DATA TRANSFER DEVICE

Abstract

A data transfer device may include: a global input/output (GIO) driver configured for driving input data and outputting the driven data to a first GIO line, and configured for using a second supply voltage lower than a first supply voltage as a source voltage to drive the input data; and a repeater configured for amplifying data applied to the first GIO line, outputting the amplified data to a second GIO line, and shifting the data applied to the first GIO line to a level of the first supply voltage. The repeater may drive the data applied to the first GIO line to a first node, drive an output of the first node to the second GIO line, and reset the first node to the level of the first supply voltage based on a reset signal before a read operation.
