  • Patent number: 8477557
    Abstract: Disclosed is an input circuit of a semiconductor memory apparatus. The input circuit includes a first buffer and a second buffer. The first buffer has an input terminal connected with a first input pin for receiving a control signal used in a multi-control mode for controlling an entire memory area by dividing the entire memory area, and an output terminal having a first level according to a control mode signal. The second buffer has an input terminal connected with a second input pin for receiving one of plural signals used in a single control mode for controlling the entire memory area without dividing the entire memory area, and an output terminal having a second level according to the control mode signal.
    Type: Grant
    Filed: September 30, 2011
    Date of Patent: July 2, 2013
    Assignee: SK hynix Inc.
