The discharger discharges the electric charges of the first node when the amount of electric charges of the first node is equal to a predetermined value. | 2015-04-02 |
20150092505 | SEMICONDUCTOR DEVICE INCLUDING PLURAL CHIPS STACKED TO EACH OTHER - A method for reading data from a plurality of DRAM devices connected to common command, address, and data busses. A clock signal is provided to the plurality of DRAM devices. A read command and address to the plurality of DRAM devices on the command and address busses in synchronization with the clock signal. A read clock signal is provided to the plurality of DRAM devices to initiate a read operation in one of the plurality of DRAM devices that is selected by the address. The one DRAM device delays the read clock signal by an amount based on a speed of the one of the plurality of DRAM devices to generate. First delayed read clock and second delayed read clock signals are provided. The read data is received on the data bus in synchronization with the second delayed read clock signal. | 2015-04-02 |
