The present invention discloses a charge trap flash memory cell with multi-doped layers at the active region, a memory array using of the memory cell, and an operating method of the same. The charge trap memory cell structure of the present invention is characterized by forming multi-doped layers at the active region appropriately, and it is a difference from the conventional art. The present invention induces electrons to band-to-band tunnel at the PN junction with the source/drain region by the multi-doped layers, and accelerates the electrons at the reverse bias to generate an avalanche phenomenon. Therefore, the method for operating a memory array of the present invention comprises programming by injecting holes which are generated by the avalanche phenomenon into multi-dielectric layers of each memory cells, and erasing by injecting electrons through an F-N tunneling from channels into the multi-dielectric layers of each memory cells.

A driving apparatus for an organic light-emitting diode includes an organic light-emitting diode, a driving switch that drives the organic light-emitting diode in response to a control voltage applied to a gate terminal of the driving switch, a high-level voltage source that supplies a high-level voltage to the driving switch, a data driving circuit that supplies a data voltage to a data line of the driving apparatus, a reference voltage source that supplies a reference voltage to the driving apparatus, and a capacitor that applies the control voltage to the gate terminal of the driving switch, the control voltage being a difference between the data voltage and the reference voltage.
摘要:
A mobile storage system is disclosed that in one aspect identifies a geographical location change of a user, such as movement from a first geographical location to a second geographical location. In response, the mobile storage system may move the user's information to a storage device associated with the second geographical location so that the user's information may be accessed by the user more efficiently.
摘要:
Disclosed is an air conditioner that can operate in a general cooling mode in which indoor air is cooled by heat exchange with a first refrigerant in a main evaporator, or alternatively in a fast cooling mode in which the indoor air is primarily cooled by heat exchange in a midway heat exchanger which includes the main evaporator for the first refrigerant and a fast cooling condenser for a second refrigerant, and then re-cooled in a fast cooling evaporator for the second refrigerant. Accordingly, fast and agreeable air cooling can be achieved.
摘要:
A method of controlling an over-load cooling operation of an air conditioner includes over-load operation mode in which, when an outdoor pipe temperature and an outdoor temperature exceeds reference temperatures, respectively, the operation capacity is changed to a low-level operation capacity, which is lower than the current operation capacity, the low-level operation capacity being one of plural operation capacities set according to the operation capacities of compressors, and the operation is performed, and normal operation mode in which the outdoor pipe temperature is measured every predetermined period of time after the operation is performed in the over-load operation mode, and, when the measured outdoor pipe temperature is below the reference temperature, the operation is performed according to a signal from a thermostat. The continuous cooling operation is possible even under the over-load condition during the cooling operation of the air conditioner, and the air conditioner system is protected through the variable-capacity operation. Consequently, the present invention has the effect of improving user comfort and improving operational reliability of the air conditioner.
