  • Patent number: 6430102
    Abstract: To supply a ground potential Vss to a starter signal level shifter and a fuse information latch circuit on the basis of a fuse starter signal of which low level is shifted from the ground potential Vss to a negative voltage Vnn by the starter signal level shifter until the fuse information is latched to the fuse information latch circuit. After the foregoing fuse information is latched, a finally attained potential is supplied to the starter signal level shifter and the fuse information latch circuit. Therefore, it is possible to latch without shifting the low level, so that it becomes possible to easily shift the low level from the ground potential Vss to the negative voltage Vnn after latching.

  • Publication number: 20010014045
    Abstract: The present invention is that, in a memory circuit comprising a cell array and peripheral circuit, the cell array power source is supplied to a circuit which operates during the power-down mode in addition to the cell array. The circuit which operates during the power-down mode is, for example, a self-refresh circuit. A dynamic memory requires refreshing operations in fixed intervals even during the power-down mode. Therefore, the self-refresh circuit is operating even during the power-down mode. Thus, by supplying the cell array power source to the self-refresh circuit, it is possible to consume a prescribed quantity of current from the cell array power source generation circuit to an extent of being able to maintain the level thereof even during the power-down mode. The cell array power source may be maintained within an appropriate voltage range thereby.

  • Patent number: 6236605
    Abstract: A transistor of a driver in the semiconductor integrated circuit according to the present invention has its gate connected to a controlling circuit, and has its drain connected to a sense amplifier. The controlling circuit supplies the gate of the transistor with a gate-to-source voltage exceeding or below other power supply voltages. The drain-to-source resistance of the transistor in the on state becomes sufficiently lower as compared with that in the case of supplying the power supply voltages between the gate and source of the transistor. Accordingly, the amplifying speed of the sense amplifier is heightened without altering the sense amplifier and the driver. Besides, the amplifying speed of the sense amplifier is heightened without raising the power supply voltage which supplies the carriers to the driver.
