Abstract
A semiconductor device includes an operation flag generation circuit configured to generate an operation flag at a time when a flag period elapses from a time when an internal setting signal is generated to perform a write operation accompanied by an auto-precharge operation; and an auto-precharge pulse generation circuit configured to generate an auto-precharge pulse by shifting the operation flag by a pulse generation period set by a period code based on divided clocks generated by dividing an internal clock.
Claims20
A semiconductor device comprising:
- an operation flag generation circuit configured to generate an operation flag at a time when a flag period elapses from a time when an internal setting signal is generated to perform a write operation accompanied by an auto-precharge operation;
- and
- an auto-precharge pulse generation circuit configured to generate an auto-precharge pulse by shifting the operation flag by a pulse generation period set by a period code based on divided clocks, the divided clocks generated by dividing an internal clock.
A semiconductor device comprising:
- a shifting control signal generation circuit configured to generate a quotient code and a remainder code based on a pulse generation period;
- a pre-shifting circuit configured to generate a shifting operation flag by shifting an operation flag by a pre-shifting period set based on the remainder code, in synchronization with a first divided clock;
- and
- a shifting circuit configured to generate an auto-precharge pulse by shifting the shifting operation flag by a shifting period set based on the quotient code, in synchronization with a third divided clock.
