The ECS command generation circuit generates an ECS command based on a refresh command. The period signal generation circuit generates a sampling period signal, during a sampling period, based on the ECS command and generates an operation period signal, during an operation period, based on the ECS command. A latch error flag is generated to include information on whether errors exist in codewords during the sampling period, and an ECS operation is performed based on the latch error flag, during the operation period, for memory cells that store an erroneous codeword among the codewords."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor devices and semiconductor systems including the same","description":"A semiconductor device includes an error check and scrub (ECS) command generation circuit and a period signal generation circuit.
