The refresh time detection circuit may include a code generator configured to generate a code signal for detecting a refresh time. The refresh time detection circuit may include a latch circuit configured to generate a latch signal by latching the code signal according to a fail signal, and generate a pre-code signal and a post-code signal by latching each latch signal according to a pre-enable signal and a post-enable signal. The refresh time detection circuit may include a subtractor configured to output a refresh detection signal by performing subtraction between the pre-code signal and the post-code signal. The refresh time detection circuit may include a comparator configured to generate a detection signal by comparing the refresh detection signal with an offset signal based on the post-enable signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Refresh time detection circuit and semiconductor device including the same","description":"A refresh time detection circuit and a semiconductor device including the same may be provided.
