Patent number: 5555522Abstract: A semiconductor memory comprising a flip-flop circuit, a redundant memory cell row and column, a specific address detecting gate, a transistor, a sense amplifier and a data output buffer. The receipt of a supply potential causes the flip-flop circuit to generate previously stored output status representing the use or the nonuse of the redundant memory cell row and column. Upon detection of a specific address by the specific address detecting gate, the transistor effects a switching operation causing the output status generated by the flip-flop circuit to be output to the outside via the transistor, sense amplifier and data output buffer. This allows the use or the nonuse of the redundant bits to be verified efficiently.Type: GrantFiled: May 3, 1995Date of Patent: September 10, 1996Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Kenji Anami, Shigeki Ohbayashi, Osamu Inoue

C. was necessary.According to the process of this invention, it is possible to synthesize the crystalline complex perovskite type compounds at a low temperature of around 100.degree. C., which is 500.degree. to 700.degree. C.Type: GrantFiled: June 30, 1989Date of Patent: April 17, 1990Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Osamu Inoue, Syunichiro Kawashima
