摘要： In a storage device having a redundancy remedy function in a block unit having a memory cells array divided in plural blocks, prior to the access operation to individual memory cells in the block, the block address BA for specifying a block is entered, and block redundancy is determined in the entered block address BA, and hence it is not necessary to determine input or redundancy of the block address BA on every occasion of the access operation. As a result, the time to the access operation start to the memory cell can be shortened, and the access speed is enhanced.

摘要： A semiconductor integrated circuit device provided with an IC chip so as to prevent its circuits from malfunction when the IC chip is cracked. To detect chip cracks, a resistor R01 is disposed at the outer periphery of the area which wants to detect the chip crack. If the chip is cracked and the resistance value of the resistor R01 is changed, the resistance change is detected, thereby controlling internal signals such as the power on reset signal and stopping the whole operation of the circuit device so as to prevent the circuits from malfunction. Thus, the system security can also be improved.

摘要： The temperature measuring system using optical interference includes a light source which generates measuring light; a spectroscope which measures an interference intensity distribution that is an intensity distribution of reflected light; optical transfer mechanisms which emit light reflected from a surface and a rear surface of the object to be measured to the spectroscope; an optical path length calculation unit which calculates an optical path length by performing Fourier transformation; and a temperature calculation unit which calculates a temperature of the object to be measured on the basis of a relation between optical path lengths and temperatures. The light source has a half-width at half-maximum of a light source spectrum that satisfies conditions based on a wavelength span of the spectroscope. The spectroscope measures the intensity distribution by using the number of samplings that satisfies conditions based on the wavelength span and a maximum measurable thickness.

摘要： In the storage device of the invention, latch control is performed on a series of signals in response to latch control signals. Latch control terminals are provided to which the latch control signals are input respectively and a plurality of signal terminals to which a series of signals are input. Herein, a plurality of latch circuits is provided so as to correspond to the plurality of signal terminals, respectively. The plurality of latch circuits are located within a specified distance from their associated signal terminals respectively and within a specified distance from the latch control terminals. The delays of signal transmission from the signal terminals to their associated latch circuits can be equalized and the delays of signal transmission from the latch control terminals to which the latch control signals for executing latch control are input to the latch circuits can be equalized. This contributes to a reduction in the skew of the latch characteristics of the signals.
