The DRAMs(30,40,50) come into self refresh mode, power down mode in response to the self refresh enable signals without latency needed for entering self-refresh thereby reducing power consumption during the latency. The latency is tRASS times which is a predetermined /RAS pulse width on /CAS-before-/RAS condition of the semiconductor memory devices. Thereby it is possible to reduce power consumption by entering self-refresh without latency.

Abstract: PURPOSE: A bridge installation method is provided to reduce a term of works and construction costs and to enhance the safety of works and the construction quality by installing a single block to an appropriate spot with a continuous extrusion method by performing construction works in a block unit on the established upper structure and using a portable truss. CONSTITUTION: A bridge installation method comprises the steps of; installing a portable truss (100), which is movable to the constructing direction of a bridge from the upper part of a pier (P), over spans (P3 ¯ P4) of an established an upper structure (1) and following spans (P4 ¯ P5) of an upper structure (2)for installing and laying a gantry crane (200) self-driving along a rail (120) on the portable truss (100); assembling an upper structure (2) of the following block in the unit of an installation block on the established upper structure (1); shifting the assembled unit block to the working spot of the gantry crane (200) using a mobile chassis (300), then moving again to an appropriate constructing spot by jacking up the gantry crane (200); installing the moved unit block (2) to the appropriate installation spot from the gantry crane (200), then connecting to the established block (1); moving the portable truss (100) to the extent of a span for installing the following span (P5 ¯ P6); installing continuously by repeating the steps after assembling blocks, once completed the movement of a span of the portable truss (100).
