Patent number: 7596010Abstract: There is provided a control circuit (409) for fetching a result of a comparison of a part of bits of entry data with a corresponding bit of comparison data and prohibiting a comparison of residual bits in the entry data with the corresponding bit of the comparison data when the result of the comparison is mismatched, and the comparison of the residual bits in the entry data with the corresponding bit of the comparison data is prohibited. Consequently, the number of signal lines to be activated in one cycle of a comparing operation is decreased. Thus, a reduction in a consumed power can be achieved.Type: GrantFiled: February 12, 2008Date of Patent: September 29, 2009Assignees: Hitachi, Ltd., Hitachi ULSI Systems Co., Ltd.Inventors: Masahiko Nishiyama, Keiichi Higeta, Takashi Koba

Patent number: 7428682Abstract: In relation to the built-in self-test circuit (BIST circuit) for testing CAM macros, the present invention is intended to provide a means to enable reduction in amount of materials as required for wiring channel region for signal distribution, buffer, FF, etc., and in number of LSI pins, and further, to facilitate mounting on chips. The data generators for CAM testing, inserted between the APG for RAMs and CAM macros, create data to write to the CAM macros by obtaining the address signals directly or by decoding the same signals. The APG is common to all the memory macros, and testing proper to each CAM can be carried out by changing over the operation of the inserted data generators by means of the control signal. The data generators are arranged in the proximity of the CAM macros, the circuits to be tested.Type: GrantFiled: January 20, 2006Date of Patent: September 23, 2008Assignee: Hitachi, Ltd.Inventors: Yoichiro Aihara, Masahiko Nishiyama, Daisuke Sasaki

Patent number: 7320482Abstract: The invention intends to provide a technique that achieves a sufficient phase margin with ease. The circuit includes a power supply circuit that is formed with a phase compensating resistor and a phase compensating capacitor, between a second input terminal of a differential amplifier and a low supply voltage. Thereby, the first pole frequency in the overall gain is determined by the first pole frequency in the voltage-dividing resistor stage in the Bode diagram for the pole/zero compensation, which is shifted to a lower frequency. Also, the zero point cancels the first pole frequency in the differential amplifier stage, which reduces the phase delay to secure the phase margin.Type: GrantFiled: April 3, 2007Date of Patent: January 22, 2008Assignees: Hitachi ULSI Systems Co., Ltd., Renesas Technology Corp.Inventors: Hiroshi Toyoshima, Masahiko Nishiyama
