摘要:
A column address is decoded by each column decoder, and an arrangement of pixels to be written to a memory cell array is rotated by a rotation circuit. The rotation result is written to the memory cell array in accordance with the decoding result of the column address. Then, the column address is decoded by each column decoder to a decoding result which is different from the decoding result of the column address at the time of writing. In accordance with the decoding result, pixels stored in the memory cell array are read. The arrangement of the read pixels is rotated by the rotation circuit and then outputted. Thus, rearrangement of pixels constituting an image can be carried out quickly while avoiding any increase in the size of the device.

A system for controlling a speed of a vehicle having a continuously variable transmission (CVT) and a cruise controller which controls the traveling speed of the vehicle to a desired speed in response to an instruction to cruise control inputted by a vehicle operator. In the system, the speed ratio is fixed to a value, at which the instruction to cruise control is inputted, for a predetermined period of time since inputting of the instruction to cruise control. The speed ratio may be fixed to the value until the throttle opening has stabilized or the vehicle speed is equal to the desired vehicle speed even after the predetermined period of time has elapsed. Alternatively, a parameter indicative of upslope of the road where the vehicle climbs is determined and the speed ratio may be controlled-based on the parameter and the vehicle speed, or thereafter until the throttle opening has stabilized or the vehicle speed is equal to the desired vehicle speed. With this, the system can reduce throttle opening change and can decrease variation in vehicle speed when the cruise control is effected.

A control of a flash memory includes control for supplying a pulse-shaped voltage to each of non-volatile memory cells until a threshold voltage of the non-volatile memory cell having a first threshold voltage is changed to a second threshold voltage. The control involves a first write mode (coarse write) in which the amount of change in threshold voltage of each non-volatile memory cell, which is varied each time the pulse-shaped voltage is applied, is relatively rendered high, and a second write mode (high-accuracy write) in which the amount of change in threshold voltage thereof is relatively rendered low. As compared with the high-accuracy mode, the number of pulses required to change the threshold voltage of each memory cell is smaller than that in the coarse write mode. Therefore, the number of verify operations at the time that the coarse write mode is used, is small and hence the entire write operation can be speeded up.

For a semiconductor integrated circuit having an internal booster circuit such as a flash memory, voltage booster circuits capable of generating a boosted voltage 10 times or more as high as a relatively low source voltage is to be realized. Charge pumps for carrying out first stage voltage boosting on the basis of a source voltage are configured of parallel capacity type units, and charge pumps for carrying out second stage voltage boosting on the basis of the boosted voltage generated by the first charge pumps are configured of serial capacity type units.
摘要:
In a nonvolatile semiconductor memory device in which a plurality of threshold values are set to store multi-level data in a memory cell, bits of multi-bit data are separately written into a memory cell according to an address signal or a control signal to effect the reading and erasing. Concretely, the memory array is so constituted that it can be accessed by three-dimensional address of X, Y and Z, and multi-bit data in the memory cell is discriminated by the Z-address.

A tire (12) used includes a steel belt in its outer circumferential portion. A magnetic sensor (14) including a pair of magnetic detection elements (18A, 18B), which are arranged so that their magnetic detection directions become parallel to each other or series each other, is set in the vicinity of a rear tire (12) in a trunk room of a vehicle (10). Changes in magnetic field upon revolution of the tire (12) are differentially detected by the magnetic detection elements (18A, 18B), and the revolution of the tire (12) is detected on the basis of the differentially detected output waveform. Among a plurality of peaks present in the differentially detected output waveform, a peak, the potential difference from the immediately preceding peak of which is equal to or larger than a predetermined threshold value, is detected as an effective peak, which is effective for tire revolution detection, and the revolution speed of the tire is calculated by detecting the number of effective peaks.

摘要:
A color-filter manufacturing method which manufactures a color filter where occurrence of color mixture and colorless portion(s) are prevented while improving ink-arrival precision in applying ink onto a substrate. The method manufactures a color filter by discharging ink from an ink-jet head IJH on a substrate 53 so as to color respective pixels with a plurality of discharge ink. When ink I2 discharged from the ink-jet head IJH is applied not in the form of ink droplet but in the form of pillar onto the substrate 53, the ink I2 is applied at a position within a pixel, where the ink I2 is to mix with previously-applied ink I1.
