IPC: H01L27/108
Filed: 1991-11-22
Abstract: PURPOSE:To obtain a DRAM to show the constant life of a TDDB without depending on a process variation by a method wherein the operating point of a reference voltage generating circuit is set in such a way that a variation in a reference voltage to a variation in the gate oxide film thickness of a MOS transistor satisfies a specified relation. CONSTITUTION:In this DRAM, the operating point of a reference voltage generating circuit 1 is set in such a way that a variation  Vref in a reference voltage Vref to a variation  Tox in a gate oxide film thickness Tox of a MOS transistor satisfies the formula. Accordingly, a word line drive voltage VWL obtainable by multiplying a constant amplification factor to the voltage Vref is also proportional to the film thickness Tox. According to such a way, when the film thickness Tox is varied by a process variation, the voltage VWL is also varied in proportion to the variation. After all, an electric field which is applied to a gate oxide film is always kept constant without depending on the variation in the film thickness Tox. Accordingly, there is not the deterioration of a TDDB due to irregularity in the gate oxide film thickness. Moreover, a temperature variation can be also eliminated by specified conditions.

Title: Method and apparatus for separating fault position in optical transmission line
Inventor: TOMITA NOBUO
IPC: G01M11/00
Filed: 1989-11-27
Abstract: PURPOSE:To separate the fault positions in a transmitting apparatus and an optical transmission line accurately from the inside of an office by inserting two or more light reflectors at the far end side of the optical transmission line under test, and transmitting testing light pulses from the near end of the optical transmission line under test to the far end side. CONSTITUTION:The testing waveform of a light pulse tester 1 is shown by a solid line 8 at the normal time. Two reflected waveforms 8a and 8b can be detected with two light reflectors 4a and 4b. When a fault is present in an optical fiber section from an office to the first light reflector 4a, the light pulse testing waveforms are shown as a reflected waveform 9 and a reflected waveform 10. In the case of the reflected waveform 9, an optical fiber 2 is broken in the vicinity of the first light reflector 4a under the state wherein the same reflecting attenuation amount as the light reflector 4a is found. In the case of the reflected waveform 10, reflection is hardly found. Therefore, when the fault occurs in the optical fiber 2, the two reflected waves from the light reflectors 4a and 4b become one or zero. Thus, the faults can be separated as follows. When the number of reflections appearing as the test waveforms is two, the fault is in a transmitting device 3. In the other case, the fault is in the optical fiber 2.
