摘要： A semiconductor device for generating first and second internal clocks complementary with each other from an external clock and usable for both a system of a type using a complementary clock and a system of a type generating a 180° phase clock internally, is disclosed. A first clock input circuit (buffer) is supplied with a first external clock and outputs a first internal clock. A second clock input circuit (buffer) is supplied with a second external clock complementary with the first external clock and outputs a second clock. A ½ phase clock generating circuit generates a ½ phase shift signal 180° out of phase with the first internal clock. A second external clock state detection circuit judges whether the second external clock is input to the second clock input buffer. A switch is operated to produce the second clock as the second internal clock when the second external clock is input and to produce the ½ phase shift signal as the second internal clock when the second external clock is not input, in accordance with the judgement at the second external clock state detection circuit.

摘要： The present invention is that in a dynamic memory circuit, first and second internal operation cycles are assigned to one external operation cycle according to external commands, a memory core performs a read operation which corresponds to a read command at the first internal operation, and performs a refresh operation which responds to a refresh command at the second internal operation cycle. Also the memory core performs a refresh operation which responds to a refresh command at the first internal operation cycle, and performs a write operation which corresponds to a write command at the second internal operation cycle. It is preferable that when the read or write command is not input, the refresh operation is performed at the earlier internal operation cycle. And a refresh command generation circuit which generates the refresh command at a refresh time is created in the memory circuit.

摘要： A data signal is output from an output circuit of a first chip and sent to a data input terminal in the second chip via a data lead line based on an output clock in first chip, which is sent to the second chip. And an input circuit in a second chip receives the data signal and transfers it inside in response to a transfer clock that has been generated from the output clock in the first chip. In synchronism with a single reference clock in the first chip, therefore, a data signal can be transferred to the second chip from the first chip at a high speed.

摘要： A semiconductor memory device manufactured separately is connected to an interface unit of a semiconductor device. An internal memory formed in the semiconductor device is connected to at least a part of the interface unit. A memory selecting circuit makes the internal memory accessible in a first operation mode, and makes the internal memory inaccessible in a second operation mode. Therefore, for example, putting the semiconductor device into the first operation mode and accessing the internal memory enables the semiconductor device to operate as a predetermined system even when the semiconductor memory device is not connected to the interface unit. The substitution of the internal memory for the semiconductor memory device makes it possible for the semiconductor device to test the interface unit and associated circuits thereof by itself. This consequently allows improvement in the assembly yield of multichip modules.

摘要： A command receiver circuit receives a command signal in synchronization with either a rising edge or a falling edge of a clock signal. A data input/output circuit starts an output of read data and an input of write data in synchronization with the edges of the clock signal which are set in response to reception timing of the command signal. Since the command signal can be received in synchronization with both edges of the clock signal, it is possible to halve a clock cycle when a reception rate is the same as that of the conventional art. As a result of this, in a system on which the semiconductor memory device is mounted, it is possible to halve the frequency of a system clock and to reduce power consumption of a clock synchronization circuit in the system, without reducing a data input/output rate for the semiconductor memory device.
