Disclosed is an operating method of a flash memory device, which includes normal memory cells and dummy memory cells. The operating method includes programming the normal memory cells and programming the dummy memory cells. A dummy pass voltage used for programming the dummy memory cells is different from a normal pass voltage used for programming the normal memory cells.

A lock-out circuit is adapted to selectively perform a lock-out function in an integrated circuit device. The lock-out function cuts off the supply of an operating voltage to the integrated circuit device whenever a power supply voltage for the device falls below a predetermined detection voltage. However, the lock-out function is disabled whenever the integrated circuit device performs an operation requiring a power supply voltage lower than the predetermined detection voltage.

An optical fiber cable includes a plurality of loose tubes and an outer jacket for binding the loose tubes is disclosed. Each of the plurality of loose tube includes one or more optical fibers; an inner jacket for binding the optical fibers; and an antistatic fluid applied between the optical fibers to prevent or reduce the generation of static electricity between the optical fibers.

Operation methods of charge-trap flash memory devices having an unused memory cell for data storage and a normal memory cell used for data storage are discussed. The operation method may include selecting the unused memory cell, and programming the unused memory cell to have a predetermined threshold voltage. The charge-trap flash memory device may thus be provided with improved reliability by interrupting erasure stress to unused memory cells.

摘要:
An optical fiber cable suitable installation using an air-blown method is disclosed. The optical fiber cable has a center tensile member located at a center of the optical fiber cable to provide tension-resistant force, at least three loose tubes each of which includes at least one optical signal transmitting medium, and located to surround a peripheral portion of the center tensile member, a binder surrounding the loose tubes to maintain an alignment pattern of the loose tubes, and a sheath located at an outermost portion of the optical fiber cable. The optical fiber cable has a polygonal sectional shape having smooth edges.
