  • Patent number: 6252269
    Abstract: According to a semiconductor memory for one aspect of the present invention, a memory cell transistor is formed in a P-type first well region which is formed at the surface of a P-type semiconductor substrate, and a back bias voltage is applied to the P-type first well region and the P-type substrate. Further, an N-type retrograde region is formed by implanting a high energy N-type impurity, so that a deeper, N-type second well region is formed by employing the N-type retrograde region. Further, a P-type third well region is formed in the N-type second well region, and a P-type emitter region is also formed therein. Thus, together the P-type emitter region, the N-type second well region, and the P-type third well region constitute a lateral PNP transistor. In addition, the ground voltage is maintained for the P-type third well region, which serves as a collector region.

  • Patent number: 6229363
    Abstract: A semiconductor device having the function of generating an internal clock signal delayed by a predetermined phase by adjusting the phase of an external clock signal, includes a first clock phase circuit for roughly adjusting the phase of the external clock signal; and a second clock phase adjusting circuit for controlling the phase of the internal clock signal with higher accuracy than the first clock phase adjusting circuit. The semiconductor device having such a construction executes phase comparisons by the first and second clock phase adjusting circuits independently of each other, and when a phase control operation by the second clock phase adjusting circuit is made subordinate to that of the first clock phase adjusting circuit, the delay time of each of a plurality of delay elements inside the first clock phase adjusting circuit is set to a value larger than a power source jitter resulting from a noise of a power source and a jitter of the external clock signal.
