    Abstract: A semiconductor memory device includes mini arrays and a serial-parallel conversion circuit. The serial-parallel conversion circuit simultaneously writes two continuous data into mutually different mini arrays out of plural data that are continuously input synchronously with an internal clock, and continuously outputs two data simultaneously read from different mini arrays, synchronously with the internal clock. In testing the semiconductor memory device according to the present invention, one data is written during a period when an external clock having a cycle of an integer times cycle of the internal clock is fixed to a high level or a low level. With this arrangement, continuous data can be assigned to mutually different mini arrays.

    Abstract: A PLL circuit includes a phase comparator for outputting a frequency control signal based on a result of comparison between phases of an input reference clock signal and a fed-back oscillation signal; an oscillation circuit, connected to the phase comparator, for outputting an oscillation signal having a frequency in accordance with the frequency control signal, a power source voltage, and a predetermined reference voltage; and a bias control circuit, connected to the oscillation circuit, for increasing either the potential difference between the reference voltage of the oscillation circuit and a ground voltage or the potential difference between the power source voltage of the oscillation circuit and the ground voltage. A transistor in the oscillation circuit can operate in a saturation area, thereby operating the PLL circuit at a high speed with a low power source voltage, without being easily affected by a variation in the temperature or other process conditions.

    Abstract: A delay adjusting circuit that can minimize a delay at selectors even when the number of delay stages and the number of selector stages are increased, to enable a stable and speedy operation. As selectors S in a delay producing circuit (11), 2:1 selectors, each of the type that selectively outputs one from two inputs, may be used which are connected to input/output portions of N-stage delay elements D1 to DN for enabling delayed output of an even-stage delayed clock signal (Even) and an odd-stage delayed clock signal (Odd). In this case, the 2:1 selectors are arranged in a two-stage configuration including the for-even-stage selectors (S1, S3, . . . , Sn, S(n+2)) and the for-odd-stage selectors (S2, . . . , S(n+1), S(n+3)). The even-stage delayed clock signal (Even) is obtained through the first-stage selector S1. The odd-stage delayed clock signal (Odd) is obtained through the second-stage selector S2.
