    摘要: Normal column selection signal switching device (20) is provided to switch a signal outputted from normal column selection signal generating device (19) in response to a test-mode signal (TMC1). Even if the normal column selection signal generating device (19) outputs a signal to disable a normal column decoder (3), the normal column selection signal switching device (20) switches the signal to enable the normal column decoder (3) to operate in the test operation. Having this configuration, a semiconductor memory device enables writing of data into all the normal memory cells even after some of the normal memory cells are replaced by spare memory cells.

    摘要: A semiconductor memory device includes a first conductivity type well in a first conductivity type semiconductor substrate surrounded by a second conductivity type well, one of a memory cell and an external input circuit arranged on the first conductivity type well and the other disposed outside the second conductivity type well. A predetermined power supply voltage is applied to the second conductivity type well and the first conductivity type well is connected to ground. In the structure, charge carriers injected from the external input circuit are absorbed in the second conductivity type well. As a result, the charge carriers are prevented from reaching the memory cell and destroying data stored therein. Therefore, it is possible to miniaturize transistors and increase integration density of dynamic random access memory devices without degrading the source to drain dielectric strength.

    摘要: In a tandem mill system, at least one first type rolling mill is arranged in the upstream side and at least one second type rolling mill is arranged in the downstream side. The first type rolling mill is of the so-called work roll crossing mill in which a pair of work rolls are inclined with respect to a pair of back-up rolls supporting the work rolls and simultaneously crossed each other in a horizontal plane to control transverse thickness distribution of a strip. The second type rolling mill is of the so-called HC mill which controls the strip crown and shape by a combination of axial movement of intermediate rolls and work roll bending. Such an arrangement makes it possible to increase a capability of controlling the strip crown and shape, particularly, a capability of correcting the quarter buckle, and eliminate a fear of causing scratches on the strip and roll surfaces, with the result of improved production efficiency. Plural lines of lubricant supply device are also provided to stop supply of a lubricant immediately before biting of the strip into the work roll crossing mill and start the supply again after the biting. A system of lubricating the work roll crossing mill is thereby improved.

    摘要: To eliminate a vertically asymmetrical deflection, a rolling mill comprises a device for measuring horizontal deflections of upper and lower work rolls 2, 3 during rolling, a device for comparing values measured on the upper and lower sides and calculating the difference therebetween, and a horizontal deflection controller four determining whether the difference exceeds a predetermined range or not and imparting a horizontal bending to at least one of the work rolls. To eliminate a transversely asymmetrical deflection, a rolling mill comprises a device for measuring horizontal deflections of at least one of the work rolls at axially spaced positions during rolling, a device for comparing values measured on at the axially spaced positions and calculating the difference therebetween, and a horizontal deflection controller for determining whether the difference exceeds a predetermined range or not and imparting a horizontal bending to the one work roll at least one of the axially spaced positions. This prevents an adverse effect by the work rolls being horizontally deflected in a vertically or transversely asymmetrical way, reduces the diameter of the work rolls, and increases the allowable rolling load. Stable rolling of high-quality strips with good shape or flatness is thus achieved.
