A handheld information device, including: a display part to display one or more control menus; and a controller to calculate a velocity of a vehicle, and to control the display part to display an enlarged control menu relatively increased in size than a predetermined control menu on the display part if the calculated velocity is faster than a predetermined reference velocity.

Handheld information device and control method thereof

A semiconductor memory device and manufacturing method, including a bit line connector and a lower electrode connector that respectively connect a bit line and a capacitor lower electrode of the device to active areas of a semiconductor substrate. The connectors are formed using a line-type self-aligned photoresist mask pattern positioned on an interlevel dielectric layer formed on the substrate, which exposes only a portion of the dielectric layer corresponding to a source region and which extends in a direction which a gate electrode extends, to provide a misalignment margin. The bit line connector and the lower electrode connector are respectively formed by one-time mask processes. A contact hole for the bit line connector in a cell area, and a contact hole for a metal wiring plug in a peripheral area are simultaneously formed, alleviating etching burden during subsequent forming of a metal wiring pad.
