Self-refresh control circuit for detecting current flowing from current generator and semiconductor device including same |
摘要 |
A self-refresh control circuit includes a first constant current generating circuit that generates a constant current to change depending on the temperature, a second constant current generating circuit to generate a constant current not depending on the temperature, a current-cycle converting circuit selectively connected to the first constant current generating circuit and the second constant current generating circuit and converting the constant currents inputted from the first constant current generating circuit and the second constant current generating circuit into a test refresh cycle used for setting the refresh cycle.
