Abstract: Disclosed is a high voltage output device having a serial-parallel stack structure of capacitors. The high voltage output device includes a substrate includes a capacitor element and a pillar structure provided on an upper surface of the substrate. The substrate includes a first electrode and a second electrode, which have different potentials from each other. The capacitor element is connected to at least one of the first electrode and the second electrode.

Abstract: A pseudo dual port memory device in which an operating speed is improved and stability is increased is provided. The pseudo dual port memory device may include a memory cell, a pair of bit lines connected to the memory cell, a write driver, a sense amp, and a column multiplexer which is connected to the bit lines, receives a write multiplexer control signal and a read multiplexer control signal, connects the bit lines to the write driver in response to the write multiplexer control signal, and connects the bit lines to the sense amp in response to the read multiplexer control signal. A precharge control signal generation circuit which is connected to the column multiplexer may generate a precharge control signal on the basis of the read and write multiplexer control signals, and a bit line precharge circuit may precharge the bit lines based on the precharge control signal.

Abstract: A hemicyanine dye having formula (1) and an optical recording medium using the hemicyanine dye as an optical recording medium are provided: wherein Z is a benzene ring, naphthalene ring or anthracene ring; X1 is S, O, Se, NR or C(CH3)2; X2 is S, NR or O, where R is hydrogen or an alkyl group of 1 to 5 carbon atoms; R1 is hydrogen, halogen atoms, an alkyl group of 1 to 3 carbon atoms or a nitro group; each of R2 and R5 is an alkyl group of 1 to 5 carbon atoms; each of R3 and R4 is hydrogen, an hydroxy group, an alkyl group of 1 to 4 carbon atoms, halogen atoms or a halide; Y is Cl, Br, I, ClO4, BF4, BrO4, PF6, CH3SO3, CF3SO3, 4-CH3C6H4SO3, C6H5SO3, 6-SO3C10H6SO3 or HSO4; n is an integer of 0-2; and m is an integer of 1-2. The hemicyanine dye having formula (1) above is easy to synthesize with high yield. Thus, use of the hemicyanind dye as an optical recording medium is advantageous in terms of the manufacturing costs.
