Sun An has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).
Abstract: A buffer is disclosed. The buffer may include a buffer controller for buffering a refresh signal enabled in an auto-refresh operation synchronously with an external clock signal, a logic circuit for performing a logic operation with respect to an output signal from the buffer controller and a specific signal to output a control signal, and an internal clock generator controlled by the control signal from the logic circuit for buffering the external clock signal and generating internal clock signals.
Abstract: A buffer is disclosed. The buffer may include a buffering circuit for buffering an input signal, a buffer control circuit for outputting a first control signal which enables the buffering circuit responsive to an enable signal, and a second control signal which is enabled after the lapse of a predetermined period from a point of enable timing of the first control signal, and a logic unit for performing a logic operation with respect to an output signal from the buffering circuit and the second control signal from the buffer control circuit.
