Abstract: A method and apparatus to reproduce a media file including reading mapping information from a predetermined position of the media file, searching for a sound field effect file of the media file by referring to the mapping information, and setting an equalizer of the audio data on the basis of the sound field effect file. A user can reproduce a media file by using an optimized equalizer of each media file even though the user himself does not set the equalizer. Also, since an equalizer setting of the reproducing apparatus can be applied to another reproducing apparatus, a user can enjoy listening to a media file in the other reproducing apparatus under the same reproducing conditions as those of the reproducing apparatus.

Abstract: A high density semiconductor device is provided with an improved voltage pumping (bootstrapping) circuit. The voltage pumping circuit generates at an initial power-up state a first output voltage which is substantially identical to the memory device source supply voltage. The pumping circuit then pumps the first output voltage up to a second output voltage which is higher than the first output voltage. The pumping operation is achieved prior to or upon the semiconductor memory device being enabled in response to a series of pulses output from an oscillator.

Each of the memory cells has a transistor and a capacitor connected serially between one of bit lines successively along the row and a fixed voltage source. Word lines are respectively connected to gates of the transistors of the memory cells for activating the memory cell selectively according to row address. The sense amplifier has a cross-coupled bistable flip-flop connecting the bit lines to each other in the row. A latch transistor connected to the flip-flop detects and amplifies a voltage difference between the bit lines. The bit lines are equalized and precharged with a reference voltage in response to a clock control signal. A cross-coupled pair of transistors also connecting the bit lines to each other transfer a charging voltage to the bit lines.
