    摘要： A voltage generating circuit, in which the influence of offset of an amplifier on an output voltage is reduced, has first and second bipolar transistors (Q1, Q2) having emitter terminals at the same electric potential. A base terminal of Q1 is disposed on a collector side of Q2. A first resistance element connects the collector side of Q2 with the base side of Q2; and a second resistance element (R1) connects a collector side of Q1 to R2. A third resistance element (R3) connects a base terminal of Q2 with the electric potential of the emitter terminals. An amplifier (A1) outputs a voltage based on a voltage difference between the collector sides of Q1 and Q2; and a voltage-current converting section (MP1, MP2) converts amplifier output into a current supplied to the connection node of R1 and R2. A voltage is then output on the basis of the generated current.

    摘要： The present invention provides a semiconductor memory circuit capable of reducing current consumption at non-operation in a system equipped with a plurality of chips that share the use of a power supply, address signals and a data bus. The semiconductor memory circuit has an internal circuit which is capable of selectively performing the supply and stop of an operating voltage via switch means and includes a memory array. An input circuit, which receives a predetermined control signal therein, controls the supply and stop of the operating voltage by the switch means to reduce a DC current and a leak current when no memory operation is done, whereby low power consumption can be realized.

    摘要： In a semiconductor device having a data input buffer capable of inputting write data to each of memory units, the data input buffer is changed from an inactive state to an active state after the reception of instruction for a write operation effected on the memory unit. The data input buffer is a differential input buffer having interface specs based on SSTL, for example; which is brought to an active state by the turning on of a power switch to thereby cause a through current to flow and receives a signal therein while immediately following a small change in small-amplitude signal. Since the input buffer is brought to the active state only when the write operation's instruction for the memory unit is provided, the data input buffer is rendered inactive in advance, before the instruction for the write operation is provided, whereby wasteful power consumption is reduced. In another aspect, power consumption is reduced by changing from the active to the inactive state in a time period from a write command issuing to a next command issuing.

    摘要翻译： 在具有能够向每个存储单元输入写入数据的数据输入缓冲器的半导体器件中，在接收到对存储器单元进行的写入操作的指​​令之后，数据输入缓冲器从非活动状态改变为有效状态。 数据输入缓冲器是具有基于SSTL的接口规范的差分输入缓冲器; 通过电源开关的导通而使其成为活动状态，从而在紧接着小振幅信号的小变化之后立即进行通过电流的流动并接收信号。 由于只有在提供了写入操作对存储器单元的指令的情况下，输入缓冲器才进入活动状态，所以在提供写入操作的指​​令之前，预先使数据输入缓冲器无效，从而减少浪费的功耗。 在另一方面，通过在从写入命令发布到下一个命令发布的时间段内从主动状态变为非活动状态来降低功耗。

    摘要： Method for manufacturing a memory device, the memory being a memory array with a spare bit line and being provided with a defect recovery scheme featuring a redundancy circuit. The redundancy circuit includes one or more comparing circuits having programmable elements which function as a memory for storing therein a defective address existing in the memory array. The programmable elements of the redundancy circuit can be programmed in accordance with any of a number of different types of defect modes. Each comparing circuit of the redundancy circuit compares information (data) inputted therein, for example, the column and row addresses which may be under the control of an address multiplex system, with that programmed in the programmable elements of the comparing circuit. On the basis of this comparison, an appropriate defect recovery is effected.
