| 摘要 | A method for writing a mode register in a semiconductor device, the method includes receiving a mode register command and a mode signal, generating a first mode register setting signal, delaying the first mode register setting signal in a first latency shifter to provide a second mode register setting signal, receiving a data signal in synchronization with the second mode register setting signal, and writing the mode signal to the mode register only if the received data signal has a first logic level. | ||

| 主权项 | 1. A method for writing a mode register in a semiconductor device, the method comprising: receiving a mode register command and a mode signal; generating a first mode register setting signal; delaying the first mode register setting signal in a first latency shifter to provide a second mode register setting signal; receiving a data signal in synchronization with the second mode register setting signal; and writing the mode signal to the mode register only if the received data signal has a first logic level. | ||
