    摘要: The present invention provides a synchronous semiconductor device suitable for improving the efficiency of application of electrical stresses to the device, an inspection system and an inspection method thereof in order to efficiently carrying out a burn-in stress test. A command latch circuit having an access command input will output a low-level pulse in synchronism with an external clock. The pulse will pass through a NAND gate of test mode sequence circuit and a common NAND gate to output a low-level internal precharge signal, which will reset a word line activating signal from the control circuit. Simultaneously, an internal precharge signal passing through the NAND gate will be delayed by an internal timer a predetermined period of time to output through the NAND gate a low-level internal active signal, which will set a word line activating signal from the control circuit.

    摘要: There is intended to provide a semiconductor integrated circuit device capable of lowering the power consumption during data-write operation, enhancing operation speed, and reducing noises for stable operation. In the semiconductor integrated circuit, an active signal ACT to be inputted to a sense amplifier signal circuit SC1 is latched by a command latch circuit and outputted to a terminal N11. The terminal N11 outputs a control signal EDC1 via a timing adjusting circuit. The control signal EDC1 works to output a sense amplifier activating signal LE via a timing adjusting circuit and output buffer circuit and at the same time, the control signal EDC1 is outputted to a column switch signal circuit CS1. From the Column switch signal circuit CS1, a pulse signal is outputted via input of a control signal ACL, a pulse output circuit, and a terminal N13. In a logical circuit, AND processing is conducted between the pulse signal and an inversion signal of the control signal EDC1. Through a decode circuit, a resultant signal is outputted as switch signal CL, or CLM.
