摘要： On one hand, a row address is provided via a buffer gate to a row address register 11, and its output is provided via a complementary signal generation circuit 15 and a predecoder 16 to a word decoder 17A. On the other hand, in response to an issuance of-an activate command a control signal AS1 is provided via a delay circuit 14 to the clock input CK of the row address register 11 as a strobe signal AS2, and AS2 is provided, to reduce timing margin, via a delay circuit 20A to the strobe signal input of the predecoder 16 as a strobe signal S2. S2 is provided via a delay circuit 20B to the strobe signal input of the word decoder 17A having RS flip-flops 2301 to 2332 or latch circuits. Each of the latch circuits consists of a NOR gate having a set input and a reset input and another NOR gate having an input coupled to receive the output of the former NOR gate and another set input to receive a multiple selection signal which is common for all the latch circuits in word decoders.

摘要： A semiconductor integrated circuit producing a given output voltage includes first and second operational amplifiers, and first and second transistors. The first and second operational amplifiers detect a voltage difference between a voltage applied to an input terminal and at least one reference voltage. The first and second transistors are turned ON or turned OFF according to the levels of voltages output from the first and second operational amplifiers. The first operational amplifier receives the output voltage at the input terminal. When the level of the output voltage becomes lower than the reference voltage, the first operational amplifier allows the first transistor to operate so as to raise the output voltage. In contrast, the second operational amplifier receives the output voltage at the input terminal. When the level of the output voltage exceeds the reference voltage, the second operational amplifier allows the second transistor to operate so as to lower the output voltage.

摘要： A power supply line is formed over a memory cell array which has arranged a plurality of memory cells using a metal wiring layer M1 which is disposed on the side closest to the memory cell array, of all the metal wiring layers. The power supply lines are formed over the memory cell array using not only an upper metal wiring layer M2 but the metal wiring layer M1 so that the wiring resistance of the power supply lines may decrease and a sufficient amount of current can be supplied to the power supply lines. Consequently, the circuits supplied with an electric current through the power supply lines become capable of high-speed operation. This is particularly effective for the high-speed operation of the circuits arranged around the memory cell array. The power supply line formed using the lower metal wiring layer M1 is connected over the memory cell array to a power supply line which is formed using the metal wiring layer M2 on the upper layer than the metal wiring layer M1. Therefore, the netlike configuration of the power supply lines can be made with higher density compared to conventional ones.
