Abstract:
A method for programming a flash memory device with a plurality of memory cells. A selected memory cell is programmed under a condition where a bulk area is biased with a high voltage. A program pass/fail of the memory cell is verified with the high voltage applied to the bulk area.

Abstract:
An electric fuse circuit including a first nonvolatile memory cell connected to a first bit line, a second nonvolatile memory cell connected to a second bit line, a latch connected to the first and second bit lines, and a bias current circuit supplying one of the first and second bit lines with variable bias currents through the latch in response to a bias control signal during a test operation.
Abstract:
A vehicular steering column of a low tilt type is supported to a body at upper and lower portions thereof to be tilted in whole about a hinge joint located on the lower portion, and more particularly to a shock absorbing steering column is designed to allow a steering column to slide forward when a vehicle driver gets a secondary shock against a steering wheel due to a vehicular collision, thereby absorbing a shock. In particular, the steering column is constructed in such a manner that, in order to absorb a shock in case of the vehicular collision, shock absorbing means is provided to a lower supporting structure of the steering column, and thus an initial shock imposed on the driver can be greatly decreased.
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:
Methods and apparatuses for changing capacitance are provided. The apparatus may adjust a current supplied to a load capacitor according to the frequency of an input clock signal. When operating at a lower frequency, a capacitance may be increased such that noise immunity may be increased. When operating at a higher frequency, a capacitance may be decreased such that current consumption may be reduced.
Abstract:
Disclosed herein is a pop-up prevention structure for steering columns. This invention employs frictional force obtained by horizontally tightening a tilt lever and the engagement of a fixed gear with a movable gear, thus preventing a steering column from undesirably popping up when a vehicle is in a collision, therefore minimizing injury to a driver.
