Features include maximizing writing of data information values for successive rewrites, all-zero and all-one cell state vectors that represent a unique data information value that can be written for many generations, a very high number of writes, and does not sacrifice capacity. One embodiment comprises ordered or unordered MOH code that approaches the upper-bound for large n wits. According to the embodiments, before an erasure is needed, the majority of the wits are encoded, which provides level wearing and maximizes life of cells."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"High sum-rate write-once memory","description":"Provided are modified one-hot (MOH) constructions for WOM codes with low encoding and decoding complexity, that achieve high sum-rates.
