The memory controller is configured to detect a number of errors among the stored look-ahead bits, compare the number of look-ahead bit errors to a threshold number of bit errors, perform a strong refresh of the data and look-ahead bits stored in the resistive nonvolatile memory array when the number of look-ahead bit errors equals or exceeds the threshold, and perform a weak refresh of the data and look-ahead bits by refreshing only units of stored data having data bit errors and look-ahead bits having look-ahead bit errors when the number of look-ahead bit errors is less than the threshold."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and systems for detecting and correcting errors in nonvolatile memory","description":"A memory system includes a resistive nonvolatile memory array configured to store data and error correction code (ECC) bits and a memory controller.
