Abstract
A semiconductor system includes a first semiconductor device configured to output command addresses; and a second semiconductor device configured to generate a first control signal including a pulse controlled in its pulse width in synchronization with a toggling time of a bank active signal for selecting a bank to be activated in an active operation in response to the command addresses, a second control signal enabled in response to the bank active signal, and an internal voltage in response to the first and second control signals.
Claims15
A semiconductor system comprising:
- a first semiconductor device configured to output command addresses;
- and
- a second semiconductor device configured to receive the command addresses and generate a first control signal including a first pulse and a second pulse generated in synchronization with first to fourth bank active signals and a second control signal enabled in synchronization with a time when any one of the first to fourth bank active signals are enabled,
- wherein the second semiconductor device configured to generate an internal voltage supplied to first to fourth bank in response to the first control signal and the second control signal.
