摘要： A semiconductor memory device, such as a SDRAM, includes input/output data line pairs, data bus line pairs, and a redundancy data bus line pair. The input/output data line pairs are connected to a corresponding one of the data bus line pairs and an adjacent one of the data bus line pairs via redundancy shift switches, with a last one of the input/output data line pairs being connected to a last one fo the data bus line pairs and the redundancy data bus line pair. Sense buffers and write amplifiers are connected between each of the data bus line pairs and the redundancy data line pair. The shift switches are located closer to the input/output data line pairs than the sense buffers and the write amplifiers so that data read from the memory cells is less effected by the on resistance and the parasitic capacitance of the switches. When the switches are located closer to the data bus lines than the sense buffers and the write amplifiers are, the switches effect the data signals of data read from the memory cells.

摘要： A negative-voltage circuit for realizing a flash memory is installed independently and is applied selectively to word lines in response to signals sent from row decoders. Row decoders for specifying word lines need not be installed in the negative voltage circuit. The negative circuit can therefore be reduced in scale.

摘要： A semiconductor memory has a plurality of word lines, a plurality of bit lines, a plurality of memory cells, a differential sense amplifier, and load transistors. Each of the memory cells is a MIS transistor formed at each intersection of the word and bit lines. The threshold voltage of the MIS transistor is externally electrically controllable. The differential sense amplifier senses data stored in a selected memory cell located at an intersection of selected word and bit lines. A control pulse signal is applied to the gates of the load transistors, to bias the bit lines. The pulse width of the control pulse signal is a minimum essential to read data out of the selected memory cell. The control pulse signal controls the switching of the load transistors, to shorten a period during which a stress voltage is continuously applied to the drains of unselected memory cells that are connected to the bit line to which the selected memory cell is connected.

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 carry 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 resent 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 provided an oscillator circuit capable of obtaining stable frequency by avoiding output having unstable frequency that is likely to occur to an operation/stop-control-feasible type oscillator circuit when oscillation begins. In such an oscillator circuit, an oscillation permitting signal (EN) sets an oscillator section in oscillation-operable state, whereby a controller section starts operation. The controller section that has stared its operation change an oscillation- frequency control signal (VR) into a signal value corresponding to predetermined oscillation frequency so as to set oscillation frequency at an oscillator section. Further on, the oscillator section outputs an oscillation signal in response to a detection signal (MON) that is outputted after a detector section compares a signal inputted therein with a predetermined signal value and detects that the inputted signal reaches a predetermined signal value. Thereby, transient state of an oscillation-frequency control signal (VR) can be detected. That is, there can be avoided an output of an unstable oscillation signal due to a transient oscillation-frequency control signal (VR).

摘要： It is intended to provide a semiconductor integrated circuit device and adjustment method of the same semiconductor integrated circuit device, capable of adjusting an analog signal outputted from an incorporated analog signal generating section without outputting it outside as an analog value. An analog signal AOUT is outputted from an analog signal generating section 3 in which an adjustment signal AD is inputted. The analog signal AOUT is inputted to a judgment section 1, in which it is compared and judged with a predetermined value and then a judgment signal JG is outputted. The judgment signal JG acts on a predetermined signal storing section 4 as an internal signal and the adjustment signal AD is fetched into the predetermined signal storing section 4. Further, the judgment signal JG is outputted as digital signal through an external terminal T2 and an external tester device acquires the adjustment signal and stores the acquired adjustment signal in the predetermined signal storing section 4. Consequently, the analog signal can be adjusted as analog value without being outputted outside and an adjustment test can be carried out with a simple tester device and according to a simple test method accurately and rapidly.
