摘要： A variation in substrate voltage VBB caused by a reduction of power supply voltage VDD when an operation mode is shifted to a data retention mode is detected, and a cycle of refresh operation during this varying period is shortened or a plurality of memory cells are refreshed simultaneously, thereby enhancing the electric charge retention ability of the memory cells during this transient period. After the transient period is elapsed, the refresh cycle is returned to the original operating cycle, and the power consumption during the data retention mode can be effectively reduced.

摘要： A current mirror amplifier circuit includes a differential amplifier circuit having first and second nodes for differentially amplifying a pair of complementary input signals in an activation mode. A current mirror circuit is coupled between a first power source and the first and second nodes of the differential amplifier circuit. A switching circuit is coupled between the differential amplifier circuit and a second power source which supplies a second voltage lower than a first voltage supplied by the first power source for switching a mode of the differential amplifier circuit from a standby mode to the activation mode in response to an activation signal. A circuit is coupled between the first power source and the first and second nodes of the differential amplifier circuit for pulling up potentials of the first and second nodes during the standby mode. This circuit is deactivated after the differential amplifier circuit is switched from the standby mode to the activation mode.

摘要： An apparatus for manufacturing a laminated unit of ceramic green sheets comprises an endless belt, and an applying apparatus provided at a predetermined position on the running path of the endless belt. The applying apparatus includes a reservoir for storing a ceramic slurry and a moveable blade. When the belt runs with the blade spaced a predetermined distance from the top surface of the endless belt, the ceramic slurry flows out through a gap between the blade and the belt and, thus, is applied on the belt to a predetermined thickness. The applied ceramic slurry is dried by a drier so as to form a ceramic green sheet. A conductive paste is printed on the top surface of the ceramic green sheet by a printing apparatus. The printed conductive paste is dried by a drier. The ceramic green sheet with the conductive paste printed thereon is brought again to the applying apparatus due to the movement of the endless belt, the blade of the applying apparatus is further displaced upward, and ceramic slurry is applied on the previously formed ceramic green sheet. By repeating such applied again on the ceramic green sheet. By repeating such a process, a laminated unit of the ceramic green sheets is obtained.

摘要： The present invention provides a semiconductor memory device which reduces current consumption in a standby state owing to a suitable refresh-thinning-out function, and a refresh control method thereof. When the refresh-thinning-out function is added while a refresh operation and an external access operation are being executed independently of each other, a refresh address counter outputs a refresh address Add(C) and inputs predetermined high-order bits thereof to a refresh-thinning-out control as a high-order refresh address Add(C) (m), where judgment as to whether the refresh operation is performed, is made. A refresh permission signal RFEN corresponding to the result of judgment is inputted to a word driver to activate and control the word driver. The process of judgment by the refresh-thinning-out control circuit can be embedded in an access time of a row system.

摘要： An object is to provide a semiconductor device in which it is possible to determine whether or not a minute delay time given by a delay circuit is within a specified value or not, and a method of testing the semiconductor device. In response to a data strobe signal TDQS for testing, the delay circuits DC0 and DC1 produce delay data strobe signals IDQS0 and IDQS1 delayed by delay times DT0 and DT1. Outputted as a reverse signal from the inverter INV0, is a reverse data strobe signal RIDQS0 in response to the delay data strobe signal IDQS0, and delayed by an allowable delay time IT. Inputted into the NAND gate ND0, are the reverse data strobe signal RIDQS0 and the delay data strobe signal IDQS1. When, in comparison with the phase of the delay data strobe signal IDQS0, the phase of the delay data strobe signal IDQS1 is delayed by the allowable delay time IT or more, a pulse signal PL0 is not outputted from the NAND gate ND0.
