Abstract: Methods of operating a memory device include at least partially charging a sensing node within a page buffer of the memory device to a first precharge voltage, by sampling a trip voltage of a sensing latch within the page buffer. Thereafter, a voltage of the sensing node is boosted from the first precharge voltage to a higher second precharge voltage. Then, a voltage of the sensing node that reflects a value of data stored in a memory cell of the memory device is developed at the sensing node. The developed voltage is then transferred to the sensing latch so that data stored by the sensing latch reflects the value of data stored in the memory cell.

Abstract: An integrated circuit including first pads and second pads, a first receiver circuit and a first driver circuit respectively connected to the first pad, a second receiver circuit and a second driver circuit respectively connected to the second pad, and a first loopback circuit having a first input terminal electrically connected to the first receiver circuit, a first output terminal electrically connected to the first driver circuit, a second output terminal electrically connected to the second driver circuit, and a second input terminal electrically connected to the second receiver circuit may be provided. At a normal mode, the first loopback circuit electrically connects the first input terminal to the second output terminal and electrically connects the second input terminal to the first output terminal. At a test mode, the first loopback circuit electrically connects the first input terminal to the first output terminal.
