According to an embodiment, instead of writing a dataword directly to memory, a codeword is written to the memory location. The codeword is selected to minimize overwrite (e.g., bit-flipping) and to maximize the spread of wear across memory cells. In accordance with various embodiments of the invention, coset coding is integrated with error correction encoding; and once the previous state of a page is determined, a coset representative is selected on the basis of maximizing the number of writes to the page before erasing."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems for and methods of extending lifetime of non-volatile memory","description":"Systems and Methods are provided for increasing the number of writes to a page of non-volatile memory before the page must be erased.
