摘要： An input conversion unit converts serial data supplied from the exterior into parallel data. Each of the converted parallel data is respectively written into a plurality of memory cell areas. An output conversion unit converts parallel data constructed by data read from each memory cell area into serial data. An operational unit is activated during a testing mode so as to logically operate on the parallel data read from each memory cell area. By writing predetermined data into each memory cell area in advance, it is confirmed by a logic operation that correct data is stored in each memory cell area. The data can be checked simultaneously for the plurality of memory cell areas so that the operation test in the memory cell areas can be carried out at high speed. Besides, serial data accepted, twice per cycle of a data strobe signal, is converted into parallel data. Each of the converted parallel data is respectively written into a first memory cell area and a second memory cell area. Parallel data read from the first and second memory cell area is logically operated in a testing mode and the operation result is output at once in synchronization with the clock signal. Accordingly, the data can be checked simultaneously for the first and the second memory cell area so that the operation test in the memory cell areas can be carried out at high speed.

摘要： In the present invention, an external power source supplied to an integrated circuit device is divided into a first external power source for the DLL circuit and a second external power source for circuits other than the DLL circuit. According to the present invention, it is arranged that power source noise generated in the second external power source cannot be transmitted to the variable delay circuit by utilizing the first external power source preferably for the variable delay circuit of the DLL circuit and even more preferably for its delay unit. Also, preferably, it is arranged that power source noise generated in the second external power source cannot be transmitted to the phase coincidence detection unit by utilizing the first power source for the phase coincidence detection unit in the phase comparison circuit of the DLL circuit. Also, by connecting the first external earthing power source to the variable delay circuit and/or phase coincidence detection unit, the effect of power source noise from the second external earthing power source originating from the operation of circuits other than these is suppressed.

摘要： A command receiving circuit receives a command signal for determining a circuit operation, in synchronization with a clock signal and it outputs the received command signal as an internal command signal. An address switching circuit permits transmission of an address signal to an internal circuit upon receiving the command signal. The internal circuit receives the address signal before the reception of the command signal, thereby to start its operation. As a result, the internal circuit can be operated at high speed. Besides, the address switching circuit inhibits the transmission of the address signal to the internal circuit upon receiving the internal command signal or the clock signal. Therefore, even when the level of the address signal has changed after the reception of the command signal, the change does not lead to operating the internal circuit. Accordingly, the power consumption of the semiconductor integrated circuit is reduced. Meanwhile, the semiconductor integrated circuit comprises a plurality of memory cores and a bank switch for selecting the memory cores. The bank switch feeds the address signal to predetermined memory core(s) of the memory cores in accordance with the value of the address signal. Since the memory core can receive the address signal before the validation of a command, the circuit operation is performed at high speed even in the semiconductor integrated circuit including the plurality of memory cores are controlled as bank.

摘要翻译： 命令接收电路与时钟信号同步地接收用于确定电路操作的命令信号，并且将所接收的命令信号作为内部命令信号输出。 地址切换电路允许在接收到命令信号时将地址信号发送到内部电路。 内部电路在接收到命令信号之前接收地址信号，从而开始其操作。 因此，内部电路可以高速运转。 此外，地址切换电路在接收到内部命令信号或时钟信号时，禁止向内部电路发送地址信号。 因此，即使在接收到指令信号之后地址信号的电平变化，也不会导致内部电路的工作。 因此，半导体集成电路的功耗降低。 同时，半导体集成电路包括多个存储器核和用于选择存储器核的组开关。 存储体交换机根据地址信号的值将存储器核心的地址信号提供给预定的存储器核心。 由于存储核心可以在命令验证之前接收地址信号，所以即使在包括多个存储器核心的半导体集成电路被控制为存储体的情况下，电路操作也以高速执行。

摘要： A refresh signal is output in response to a refresh request generated at predetermined cycles, and a refresh operation is performed. The refresh operation ends when a conflict occurs between an access request and the refresh request. Consequently, an access operation corresponding to the access request can be started earlier with a reduction in access time. The access time can be reduced further by changing the end time of the refresh operation in accordance with the timing of supply of the access request. Since a test circuit for notifying the state of the refresh operation to exterior is formed, the operation margin of the refresh operation can be evaluated in a short time. As a result, it is possible to reduce the development period of the semiconductor memory.

摘要： When a test instruction signal is outputted from a command decoder, a test mode decoder receives the test instruction signal and outputs a test signal. When a DQM switch circuit receives the test signal, the DQM switch circuit outputs a mask/disable signal (MASK0 or MASK1) inputted to any one of two mask/disable terminals (DQML, DQMU) as a mask/disable signal inputted from the two terminals DQML and DQMU to a write amplifier/sense buffer. Therefore, it is possible to execute a mask/disable operation for all of input and output data with one of the two mask/disable terminals.
