  • Semiconductor device and control method in semiconductor device
    Publication number: 20070040038
    Abstract: A load detection circuit 40 detects a load value of a load portion 100 via a terminal DQ. A reference load, corresponding to the load of a probe, is output from a reference load output section. A comparison circuit 60 judges whether the detected load value matches the reference load, and outputs a control signal if matched. If this control signal is input, an input and output buffer 30 stops the output of the data from a memory cell 10 to the terminal DQ, or outputs a specific logic.

  • Waveform stabilizing drive circuit for modularized memory
    Patent number: 5883839
    Abstract: A memory drive circuit includes at least one memory module constructed of a plurality of memory elements, a memory controller for driving said memory module, and a buffer, disposed between the memory module and the memory controller, for receiving a drive signal from the memory controller and transmitting the received drive signal to the memory module. Signal reflection noises produced in the memory module are absorbed by the buffer.
