Abstract:
The present invention relates to a tilt device for allowing a steering column to be tilted so that a driver can adjust the position of a steering wheel to conform to his/her figure in order to more comfortably drive a vehicle. The tilt device of the invention has an effect in that it can impart a high supporting strength to the steering column while reliably locking the same.
Abstract:
An integrated circuit memory device includes programmed memory cells and programmable and erasable memory cells. The memory device includes a first memory array block in which programmed memory cells are arranged and a second memory array block in which programmable and erasable memory cells are arranged. The programmed memory cells in the first memory array block may be programmed with predetermined data during a semiconductor manufacturing process, and may be mask read-only memory (ROM) cells. The programmable and erasable memory cells in the second memory array block may be programmed or erased with predetermined data after the semiconductor manufacturing process, and may be electrically erasable and programmable read-only memory (EEPROM) cells or flash memory cells.
Abstract:
A word line voltage generating circuit has a high voltage generator for generating a high voltage is response to an activation signal. In addition it has a regulator circuit that includes two successive regulators. The first regulator receives the high voltage and outputs an intermediate voltage in response to a reference voltage and the activation signal. The first regulator receives the reference voltage, and adjusts the high voltage to deliver a word line voltage. The second stage includes has a depletion-type NMOS transistor, which can clamp the high voltage to a voltage of a required level.
Abstract:
A method of operating a near field communication (NFC) device includes receiving, by the NFC device, a first signal from an NFC reader, transmitting, by the NFC device, a response to the first signal to the NFC reader and changing selectively, by the NFC device, a radio frequency (RF) configuration parameter associated with signal transmission operation during a signal transmission interval, based on determining whether the NFC reader recognizes the response.
Abstract:
A memory system includes a memory and a memory controller operating to control the memory. The memory includes a random accessible memory including a memory cell array operable in a random access mode, a NAND flash memory, and a selection circuit making the memory controller operate either one of the random accessible memory or the NAND flash memory.
Abstract:
A flash memory device includes an array having memory cells arranged in rows and columns. A high voltage generator is configured to supply a high voltage to the array during a programming operation. Write buffers corresponding to selected memory cells drive the selected memory cells with a program voltage or a program-inhibition voltage in response to input data. Each write buffer consumes a dummy cell current when input data is program-inhibited data. A current-voltage conversion circuit connected to the write buffers through a common sensing line supplies a current to the write buffers as the dummy cell current through the common sensing line and outputs a voltage proportional to the current, supplied to the write buffers. A current sink circuit discharges a current from an output of the high voltage generator in response to a voltage output from the current-voltage conversion circuit.

Abstract:
The present invention relates, in general, to a tilt steering apparatus for a vehicle, and more specifically, to a tilt steering apparatus for a vehicle, capable of adjusting the angle of a steering column by engaging a movable gear with a fixed gear or disengaging the movable gear from the fixed gear, using a lock slider that does a rectilinear motion by an operation lever. If the lock slider is separated from the operation lever, even when the operation lever rotates, the lock slider does a rectilinear motion only. Hence, the lock slider and the movable gear can always make the line contact with each other. Through this line contact, the supporting rigidity and the abrasion resistance of components can be improved.
