A stacked semiconductor device including a plurality of semiconductor chips that are stacked and transfer signals through a plurality of through-electrodes, wherein at least one of the semiconductor chips comprises a first clock generation circuit suitable for generating first and second test clocks by dividing or buffering an external clock according to an operating information signal for indicating a high-speed test operation and a low-speed test operation; a first latch circuit suitable for latching a test control signal according to the first and second test clocks to generate first and second latched signals; and an input signal control circuit suitable for generating first and second internal control signals by re-latching the second latched signal according to the first test clock, and re-latching the first latched signal according to the second test clock.

Stacked semiconductor device and semiconductor system including the same

An ophthalmic composition is provided that includes rebamipide and a method for preparing the same. The ophthalmic composition of maintains its transparency for a long time even in a physiologically neutral to weakly basic pH range that does not injure the cornea and conjunctiva of a patient suffering from dry eye and has improved stability so as not to be re-dispersed.
