The memory cell array includes a plurality of memory bank arrays and each of the memory bank arrays includes a plurality of pages. The control logic circuit is configured to control the error correction circuit to perform an ECC decoding sequentially on some of the pages designated at least one access address for detecting at least one bit error, in response to a first command received from a memory controller. The control logic circuit performs an error logging operation to write page error information into the error log register and the page error information includes a number of error occurrence on each of the some pages determined from the detecting."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor memory devices, memory systems including the same and methods of operating memory systems","description":"A semiconductor memory device includes a memory cell array, an error correction circuit, an error log register and a control logic circuit.
