Abstract: A device for controlling a temperature compensated self-refresh period clamps a self-refresh signal at high temperature over a specific temperature to maintain the self-refresh period, thereby removing dependency on temperature. In the device, an oscillating signal having a period varied depending on temperature change is generated below a specific temperature, and a period of a first period signal is compared with that of the oscillating signal applied from a temperature compensated self-refresh circuit unit over the specific temperature. When the period of the oscillating signal is shorter than that of the first signal, a pulse width of an oscillating strobe signal generated in response to a plurality of division signals each obtained by dividing the period of the oscillating signal at a predetermined ratio is controlled, so that an oscillating period of the temperature compensated self-refresh circuit unit is kept at a fixed state.

Abstract: This invention provides a method for constructing a high rise building having a core and a residence space around the core, the method including the steps of: (a) installing a steel-frame pillar on a shaft portion of the core; (b) connecting a girder to the steel-frame pillar, the girder includes an anchor-connecting member to which a steel-frame beam is connected, a portion of the anchor-connecting member being buried in a core wall; (c) assembling the steel-frame beam on the anchor-connecting member; (d) arranging reinforcing bars in a deck plate or a slab type mold installed on the steel-frame beam, and in the core wall; and (e) applying a slab concrete and a core concrete simultaneously or in this order. According to the present method, the quality of the core and slab structure is improved, while providing the construction safety and saving the construction costs.
