Patent number: 5880497Abstract: A SRAM having its memory cell constructed to include transfer MISFETs to be controlled by word lines and a flip-flop circuit having driver MISFETs and load MISFETs. Plate electrodes of large area fixed on predetermined power source lines are arranged over the load MISFETs such that the plate electrodes over the offset region of the load MISFETs are formed with an opening. A silicon nitride film having a thickness permeable to hydrogen but not to humidity is formed over the transfer MISFETs and the driver MISFETs formed over the main surface of a semiconductor substrate and the load MISFETs formed of a polycrystalline silicon film deposited on the driver MISFETs.Type: GrantFiled: January 26, 1996Date of Patent: March 9, 1999Assignee: Hitachi, Ltd.Inventors: Shuji Ikeda, Koichi Imato, Kazuo Yoshizaki, Kohji Yamasaki, Soichiro Hashiba, Keiichi Yoshizumi, Yasuko Yoshida, Kousuke Okuyama, Mitsugu Oshima, Kazushi Tomita, Tsuyoshi Tabata, Kazushi Fukuda, Junichi Takano, Toshiaki Yamanaka, Chiemi Hashimoto, Motoko Kawashima, Fumiyuki Kanai, Takashi Hashimoto

Patent number: 4509147Abstract: In a static type RAM, a sense amplifier includes first and second dissymmetric type differential amplifier circuits each of which has a pair of differential transistors and an active load circuit such as a current mirror circuit connected to the drains of the differential transistors. One of balanced signals delivered from a memory cell is supplied to the non-inverting input terminal of the first dissymmetric type differential amplifier circuit and the inverting input terminal of the second dissymmetric type differential amplifier circuit. The other of said balanced signals is applied to the remaining input terminals of the first and second dissymmetric type differential amplifier circuits. As a result, notwithstanding that balanced signals cannot be delivered from each dissymmetric type differential amplifier circuit, amplified balanced signals can be obtained.Type: GrantFiled: June 1, 1982Date of Patent: April 2, 1985Assignees: Hitachi, Ltd., Hitachi Microcomputer Engineering, Ltd.Inventors: Nobuyoshi Tanimura, Sho Yamamoto, Kazuo Yoshizaki, Isao Akima
