Abstract
A semiconductor integrated circuit includes a first signal generator configured to generate a third active signal that is selectively enabled in a first duration in response to a first active signal enabled during the first duration and a second active signal enabled during at least one second duration within the first duration an internal circuit configured to cease operating in response to the third active signal, and a second signal generator configured to generate the second active signal in response to a mode determination signal and a strobe signal.
Claims18
A semiconductor integrated circuit, comprising:
- a first signal generator configured to generate a third active signal that is selectively enabled in a first duration in response to a first active signal enabled during the first duration and a second active signal enabled during at least one second duration within the first duration;
- an internal circuit configured to cease operating in response to the third active signal;
- and
- a second signal generator configured to generate the second active signal in response to a mode determination signal and a strobe signal.
A semiconductor integrated circuit, comprising:
- a driving signal generator configured to generate a first driving signal and a second driving signal that are selectively enabled during a first duration in response to first and second enable signals that are enabled during an active operation, an active command-based selection signal that is enabled during the first duration, and a control signal that is enabled during at least one second duration within the first duration;
- a bit line sense amplifier (BLSA) configured to be driven in response to the first driving signal and the second driving signal, wherein the BLSA ceases to sense when the first and second driving signals are active;
- and
- a control signal generator for generating the control signal in response to a mode determination signal and a column strobe signal.
A method for driving a semiconductor integrated circuit, comprising:
- entering a write mode;
- stopping an operation of a bit line sense amplifier in the write mode;
- loading a data on a pair of bit lines while the operation of the bit line sense amplifier is stopped;
- and
- writing the data loaded on the pair of bit lines in a memory cell.
