    摘要: There is disclosed a differential amplifier circuit wherein resistors (89, 91) and capacitors (90, 92) are connected respectively between sources of a differential pair of NMOS transistors (85, 87) and a power supply (2). The resistors (89, 91) raise the source potential of the NMOS transistors to reduce current flows during the time no transition of signal level outputted from the differential amplifier circuit occurs, reducing power consumption in the differential amplifier circuit. The capacitor (90, 92) alleviate the effects of voltage drop by the resistors (89, 91) during the signal level transition to prevent reduction in operating speed of the differential amplifier circuit.

    摘要: A synchronous semiconductor memory device according to the present invention is provided with two column address counters corresponding to two banks. The two column address counters receives two reference internal column address signals output from the two column address buffers. Each of the column address counters outputs internal column address signals successively and alternately according to the reference internal column address signals. As a result, when the access is to be performed alternately to the two banks, it would not be necessary to input an external column address signal each time the bank to be accessed changes, so that it is made possible to simplify the address input.

    摘要: In the present semiconductor device a positive, driving pump circuit is driven by an external power supply potential EXVDD (for example of 1.8V) to generate a positive voltage VPC (for example of 2.4V). A negative pump circuit for internal operation is driven by the positive voltage VPC to generate a negative voltage VNA (for example of −9.2V) required in an erasure or similar internal operation for a word line. The negative pump circuit for internal operation can have a smaller number of stages of pump and hence consume a smaller area than when the circuit is driven by the external power supply voltage EXVDD (for example of 1.8V) as conventional.
