Patent number: 7078928Abstract: The present invention provides a semiconductor integrated circuit device equipped with at least one pulse generator which generates a pulse of a pulse with shorter than a rising time up to the full amplitude of a transfer signal. A first signal and a second signal supplied from outside through a first signal path and a second signal path are respectively transferred to the pulse generator. When a rising time up to the full amplitude at any one of buffers in the first signal path and the second signal path is longer than a pulse width of a pulse to be formed by the pulse generator, the difference in phase between the first signal and the second signal is caused to correspond to a pulse width of a first pulse.Type: GrantFiled: December 17, 2003Date of Patent: July 18, 2006Assignee: Hitachi, Ltd.Inventors: Ryusuke Sahara, Kozaburo Kurita, Yuuji Suzuki, Mitsugu Kusunoki, Hideki Sakakibara

Patent number: 6714477Abstract: Read buffers (RB0-RB3) are capable of holding data read out from a plurality of memory blocks (BNK0-BNK7) that are capable of parallel operation in response to a state in which the read data cannot be externally outputted from an external interface means; and, selection means (40, 41, 42) are provided for selecting data read out from one of the memory blocks, or data read out from one of the read buffers, and for feeding it to the external interface means, while the external-output-incapable state is not present. In this way, when there is a possibility that an output of read data will cause a resource competition, this read data is stored in a read buffer, and when there is no such possibility, then the read data can be externally outputted directly, thereby improving the throughput of read data output operations.Type: GrantFiled: July 3, 2002Date of Patent: March 30, 2004Assignee: Hitachi, Ltd.Inventors: Michiaki Nakayama, Hideki Sakakibara, Toru Kobayashi, Shuichi Miyaoka, Yuji Yokoyama, Hideo Sawamoto, Masaji Kume
