Disclosed inventions include circuits and methods for controlling a plurality of data input buffers and a plurality data strobe buffers in a semiconductor memory device. High speed operation can be achieved by operating the plurality of data input buffers and the plurality of data strobe buffers in response to a buffer control signal generated faster than an input data, synchronized with internal rising and falling clock signals. A first internal falling clock signal generator generates a first internal falling clock signal in response to an external clock signal. A first internal rising clock signal generator generates a first internal rising clock signal in response to the external clock signal. A buffer controller generates a buffer control signal in response to the first and falling and rising clock signals. The plurality of data input buffers and the plurality of data strobe buffer are enabled or disabled in response to the buffer control signal.

An etchant includes: 5 to 20 wt % of persulfate, 1 to 10 wt % of at least one compound of an inorganic acid, an inorganic acid salt, or a mixture thereof, 0.3 to 5 wt % of a cyclic amine compound, 1 to 10 wt % of at least one compound of an organic acid, an organic acid salt, or a mixture thereof, 0.1 to 5 wt % of p-toluenesulfonic acid, and water, based on the total weight of the etchant. A copper-titanium etchant further includes 0.01 to 2 wt % of a fluoride-containing compound. A method of forming a display device using the etchant, and a display device, are also disclosed.

A display apparatus includes a display on which an image is displayed, an interface feasible to communicate with an image source and to receive identification information of an authentication device, which is disposed on the image source and includes the identification information, from the image source, a data storage in which at least one registration-recognition information is saved, and a controller to decide whether to display the image corresponding to an image signal received from the image source on the display based on a determination of whether the identification information received through the interface is consistent with the registration-recognition information saved in the data storage.
摘要:
A semiconductor memory device includes an advanced prefetching block for prefetching more bit data at once and effectively arranging the prefetched data so as to reduce an address access time of the semiconductor memory device. The semiconductor memory device having four pipelining latches for prefetching 4-bit data outputted from at least one bank in response to a start address of the 4-bit data and control signals includes a first data multiplexing unit, a second data multiplexing unit, a third order multiplexing unit and a forth order multiplexing unit.
摘要:
A synchronous memory device which comprises global I/O lines for data input and output from and to a memory core and a pipeline latch circuit for latching data from the global I/O lines. The synchronous memory device includes a circuit that precharges the global I/O lines when a read command signal interrupts a write operation signal, and disables the pipeline latch circuit in order to prevent write data on the global I/O lines from being latched in the pipeline latch circuit. Accordingly, the write data is prevented from being transferred to the pipeline latch circuit at an early stage of the read operation.
