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.

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： A semiconductor memory device includes two memory cell arrays, a sense amplifier shared by the two memory cell arrays; and a control circuit configured to control data readout from the two memory cell arrays. Each memory cell array includes word lines, two or more bit lines, a dummy word line, memory cells provided at intersections of the bit lines and the word lines, and dummy cells provided at intersections of selected bit lines and the dummy word line. When the control circuit reads data from one memory cell array, the control circuit activates the dummy word line included in the other memory cell array and generates, with the dummy cell included in the other memory cell array, a reference level of the sense amplifier.
