  • Semiconductor memory
    Patent number: 4903235
    Abstract: A semiconductor memory includes an array of memory cells wherein each memory cell is disposed at the intersection between a word line and a data line. An output line of the memory is coupled to the data line via transfer MOSFET and a data line signal detecting circuit, the latter being provided between the common data line and the output line. A precharging circuit for precharging the data line and a feedback circuit for coupling together the output and input sides of the data line signal detecting circuit are provided.
    Type: Grant
    Filed: May 9, 1989
    Date of Patent: February 20, 1990
    Assignee: Hitachi, Ltd.
    Inventors: Taei Kubota, Tetsuo Nakano
