  • Publication number: 20200059312
    Abstract: A method and apparatus for transmitting or detecting primary synchronization signal. The receiver receives primary synchronization signal from a transmitter, and detects the sequence used in the received primary synchronization signal by using three root indexes. Here, the primary synchronization signal is generated by using a Zadoff-Chu sequence having one of the three root indexes. The three root indexes comprise a first index and a second index, and a sum of the first index and the second index corresponds to the length of the Zadoff-Chu sequence.

    Abstract: A semiconductor device includes a delay time adjustment circuit and an address input circuit. The delay time adjustment circuit adjusts a point in time when charges are supplied to internal nodes according to a voltage level of a back-bias voltage in response to a test mode signal. The delay time adjustment circuit also delays an active signal by a first delay time varying according to amounts of charge of the internal nodes to generate a bank selection signal. The address input circuit is driven by the back-bias voltage. The address input circuit receives an address in response to the bank selection signal to generate an internal address. The address input circuit delays the address by a second delay time varying according to a voltage level of the back-bias voltage.
