Abstract: According to example embodiments, a method for operating a memory device includes receiving an on-die termination (ODT) signal through an ODT pin, and issuing a command or controlling an ODT circuit according to the ODT signal.

Abstract: A childbirth control system is provided to control the labor process of a patient. The patient's physical information of the patient and her fetus is continuously obtained during the labor via a plurality of diagnosis devices connected to a user terminal. The system includes an analysis module, which generates a childbirth progress data by continuously comparing the series of patient's measurement data with a series of reference measurement data. The childbirth progress data is provided on the user terminal to show the current progress of the childbirth as well as suggestions as to alternative childbirth method and medical treatment options. The system also provides the childbirth progress data to the user terminal of remotely located medical service providers, and allows them to remotely assist the childbirth process.

Abstract: A stacked semiconductor memory device according to the inventive concepts may include a plurality of memory chips stacked above a processor chip, a plurality of TSVs, and I/O buffers. The TSVs may pass through the memory chips and are connected to the processor chip. I/O buffers may be coupled between all or part of the memory chips and the TSVs and may be selectively activated on the basis of defective states of the TSVs.

Abstract: A semiconductor chip package includes a substrate, a first layer disposed on the substrate and a second layer substantially similar to and disposed on the first layer. The first layer has a first input/output (I/O) circuit, a first through-via connected to the first input/output (I/O) circuit and a second through-via that is not connected to the first I/O circuit. The second layer has a second I/O circuit, a third through-via connected to the second I/O circuit and a fourth through-via that is not connected to the second I/O circuit. The first through-via is connected to the fourth through-via, and the second through-via is connected to the third through-via. The package maybe fabricated by stacking the layers, and changing the orientation of the second layer relative to the first to ensure that the first through-via is connected to the fourth through-via, and the second through-via is connected to the third through-via.
