Abstract:
A method for establishing an interface between a host and a plurality of memory devices of a system that utilizes a Multimedia Card (MMC) or Digital (SD) protocol according to an interleaving scheme. A host sequentially transmits a first sequence of commands and data to a system bus in order to allow a first memory device among the memory devices to perform a first operation. The host then transmits a second sequence of commands and data to the system bus to allow a second memory device among the memory devices to perform a second operation after transmitting the first sequence of commands and data.

A scheduling method in a distributed antenna system is provided. Each of a plurality of Mobile Stations (MSs), respectively corresponding to each subchannel, are classified as a Single Transmission (ST) MS or a Cooperative Transmission (CT) MS according to a CT criterion. An MS with a maximum channel capacity is selected from among the classified MSs. Resources arc allocated to a corresponding subchannel when the selected MS is the ST MS, and resources arc allocated using a CT scheduling technique when the selected MS is the CT MS. The classifying, selecting and allocating steps are repeated until allocation of resources is completed.
Abstract:
Noise may cause malfunction and reduction of yield in semiconductor devices operating with a low supply voltage, and a logic test is generally performed for testing characteristics of input/output pads. In the logic test, High Level Input Voltage (VIH), Low Level Input Voltage (VIL), and Input Signal Fault Detection may be considered. In a normal operation mode, the noise propagates through a logic chain by toggling of the test logic circuit, and a circuit can prevent the noise propagation using logical operations. Thus, a characteristic degradation due to the noise propagation may be reduced.
