    摘要： In a semiconductor device according to the invention, first and second voltage dropping circuits, for generating voltages respectively having smaller values than that of an external power supply voltage, are provided. The first voltage dropping circuit, which consumes relatively less power, is always in the operative mode, and the second voltage dropping circuit, which consumes more power than that of the first voltage dropping circuit, is operated during an interval other than a standby interval. The voltages generated by the first and second voltage dropping circuits are supplied to an internal power supply line in parallel with each other.

    摘要： A static memory has an address transition detector, an input data transition detector and a pulse signal generator. When a detector detects that an input address or input data has changed, the pulse signal generator produces a pulse signal having a width longer than the shorter of the data-reading or data-writing cycle. This pulse signal controls the period of time during which a penetrating DC current flows between two power sources via some of the components of the memory.

    摘要： In a dynamic RAM, the refreshing operation is performed during one cycle of the read or write operation. A switch circuit selects either a row address signal output from address input circuit or a refresh row address signal output from a refresh circuit. By controlling the switch circuit by a switch selector, the refresh is performed during the operation delay time of the address input circuit or an input/output circuit for inputting and outputting data.

    摘要： In the semiconductor memory device according to the present invention, when there is a defective portion in the memory cells, those memory cells are replaced by redundant memory cells. When defective portions are discovered in the memory cells, the fuse elements corresponding to the memory cells having the defective portions are cut off. Voltages of the select lines connected to the memory cells having the defective portions are held at an L level by the resistors. Due to this, the memory cells having the defective portions are not selected.

    摘要： A semiconductor memory device has a plurality of memory cells arranged in a two-dimensional matrix array, word lines for connecting memory cells of each row to a row decoder, and bit lines for connecting memory cells of each column to a column decoder. The word lines include first word lines each of which is connected to several memory cells in each column section of one row. The word lines also include a second word line connected to the first word lines of each row through corresponding switches. In response to a column address signal, one of the switches of each row is turned on, so that one of the first word lines is connected to the corresponding second word line.

    摘要： In order to make a boundary inconspicuous, which is located between an image area which displays an image by translucent pixels and a dummy area which always displays a white color by reflection pixels, a size ratio of transparent areas in color filters of the reflection pixels with respect to reflection areas therein is made larger than a size ratio of transparent areas in color filters of the translucent pixels with respect to reflection areas therein. In such a way, brightness of the display is balanced by adjusting quantities of transmission light through the transparent areas of the reflection pixels with respect to quantities of reflection light generated unexpectedly on transmission areas of the translucent pixels. Then, degrees of whiteness in the translucent pixels and the reflection pixels are approximated to each other.
