Patent number: 8253478Abstract: An internal voltage generating circuit is provided. The internal voltage generating circuit of a semiconductor device includes a control signal generating circuit for generating a control signal according to a number of data bits, a comparator for comparing a reference voltage to an internal voltage to generate a driving signal when the control signal is inactivated, a driving signal control circuit for inactivating the driving signal when the control signal is activated, and an internal voltage driving circuit for receiving an external power voltage and generating the internal voltage in response to the driving signal. Therefore, an internal voltage can be turned to a reference voltage level or to an external power voltage level according to the number of data input and/or output bits of a semiconductor device, and even when the number of data input and/or output bits is increased, a data access speed can be improved.Type: GrantFiled: December 1, 2008Date of Patent: August 28, 2012Assignee: Samsung Electronics Co., Ltd.Inventors: Jin-Kyoung Jung, Jung-Bae Lee, Kyu-Hyoun Kim

Patent number: 7269078Abstract: Provided are a buffer circuit and a memory system for selectively outputting a data strobe signal according to the number of data bits. The buffer circuit includes a first buffer unit, a second buffer unit, and a third buffer unit. The first buffer unit amplifies and outputs a first signal. The second buffer unit amplifies and outputs a second signal or outputs the first signal according to the logic level of a control signal. The third buffer unit amplifies the first signal to send or not to send the amplified first signal to the second buffer unit depending on the logic level of an inverted control signal. The logic levels of the control signal and the inverted control signal are determined according to the number of processed data bits.Type: GrantFiled: May 31, 2006Date of Patent: September 11, 2007Assignee: Samsung Electronics Co. Ltd.Inventors: Sung-min Seo, Chul-soo Kim, Kyu-hyoun Kim, Jin-kyoung Jung

Patent number: 6999375Abstract: A synchronous semiconductor device and a method for preventing coupling between data buses. The synchronous semiconductor device supports at least two kinds of bit configuration modes and includes a first data bus and a second data bus. The first data bus is used to transmit data in a first bit configuration mode and used as a shielding line in a configuration mode other than the first bit configuration mode. The second data bus is used to transmit data in the first bit configuration mode and a second bit configuration mode and used as a shielding line in a configuration mode other than the first bit configuration mode and the second bit configuration mode. The first data bus and the second data bus are arranged alternately. In using the device and method, it is possible to prevent coupling between the data buses without additional shielding lines by using the same kind of data bus, which is not used to transmit data, as the shielding line.Type: GrantFiled: September 26, 2003Date of Patent: February 14, 2006Assignee: Samsung Electronics, Co., Ltd.Inventors: Jin-kyoung Jung, Kyu-hyoun Kim
