Abstract:
A binary image sensor according to an embodiment of the present invention comprises: binary pixels, each having a transistor structure, connected between drain lines and column lines and generating photons in response to incident light; sense amplifiers connected to column lines and detecting voltages corresponding to a current flowing through the column lines when the binary pixels apply a gate voltage to any one of the gate lines connected to gates; and an accumulator which accumulates binary output values of the sense amplifiers.

PURPOSE: A sensor, a method of operating the same and a data processing system comprising the sensor are provided to accurately measure distance information by compensating the loss of photoelectron due to thermal diffusion in a demodulating process at a sensor. CONSTITUTION: A timing controller can generate a plurality of packets(P~NP, where N is a natural number) as shown in Fig. 2c. Each of the packets(P~NP) comprises a first section(corresponding to T1 in Fig.2c; for example, referred to as an on-time section) and a second section(corresponding to T2 in Fig.2c; for example, referred to as an off-time section). During the first section, the timing controller outputs two oscillation signals(Pa and Pb), which oscillate between first and second levels, respectively. During the second section, the timing controller outputs DC voltage.

PURPOSE: A phase change memory device and a method for manufacturing the same are provided to ensure fine contact area in a phase change layer by forming nano-wire network using a porous oxide layer. CONSTITUTION: An interlayer insulating layer(100) is formed on a semiconductor substrate. A lower electrode(110) is formed on the interlayer insulating layer. A porous insulating layer(120) is formed on the lower electrode. A single element-based phase change layer(130) is formed on the porous insulating layer. An upper electrode(140) is formed on the phase change layer. In case of the formation of the single element-based phase change layer, a nano-wire network phase change layer is simultaneously formed in the porous insulating film.
