    Abstract: A semiconductor device includes a substrate, a conductive pattern, a side spacer, and an air gap. The substrate includes an interlayer insulating layer and a trench penetrating the interlayer insulating layer. The conductive pattern is disposed within the trench of the substrate. The side spacer is disposed within the trench. The side spacer covers an upper side surface of the conductive pattern. The air gap is disposed within the trench. The air gap is bounded by a sidewall of the trench, the side spacer, and a lower side surface of the conductive pattern. A level of a bottom surface of the conductive pattern is lower than a level of bottom surfaces of the side spacer.

    Abstract: A refresh address generator may include a lookup table including a first portion storing a first group of addresses associated with a first data retention time, and a second portion storing a second group of addresses associated with a second data retention time different from the first data retention time, wherein the addresses of the first portion are more frequently accessed than the addresses of the second portion to refresh the memory cells corresponding to the addresses. Systems and methods may also implement such refresh address generation.

    Abstract: A buffer circuit is provided which is insensitive to a duty distortion regardless of the change of operation environment. The buffer circuit includes a current mode logic buffer and a differential-to-single-ended converter. The differential-to-single-ended converter receives first and second differential output signals to generate a single ended output signal and is configured so that an internal control node of the differential-to-single-ended converter is controlled in a negative feedback method to maintain a constant duty ratio of the single ended output signal regardless of the change of operation environment. According to some embodiments, a duty distortion of the single ended output signal due to the change of operation environment such as a process, a voltage, a temperature, etc. is reduced or minimized and thereby performance of the buffer circuit is improved and operation reliability is improved.

    Abstract: A GNSS receiver includes a RF unit, a baseband processing unit, a storage unit, a mode control unit and a counter unit. The RF unit receives a satellite signal from an external satellite. The baseband processing unit determines present operation environment of the GNSS receiver based on the satellite signal. The storage unit stores information received by the RF unit and information generated by the baseband processing unit. The mode control unit controls an operation mode of the GNSS receiver based on the present operation environment. The operation mode includes a normal mode and a low power mode. The counter unit counts a first number representing a number of consecutive times in which the GNSS receiver has entered the low power mode. When the GNSS receiver enters the low power mode, the mode control unit turns off at least one of the RF unit, the baseband processing unit and the storage unit based on the first number.
