The apparatus includes memory cells connected to word lines including at least one edge word line and other data word lines. The memory cells are arranged in strings and are configured to retain a threshold voltage corresponding to data states. The strings are organized in rows and a control means is coupled to the word lines and the strings and identifies the at least one edge word line. The control means programs the memory cells of the strings in particular ones of the rows and associated with the at least one edge word line to have an altered distribution of the threshold voltage for one or more of the data states compared to the memory cells of the strings not in particular ones of the rows and not associated with the at least one edge word line during a program operation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Edge word line data retention improvement for memory apparatus with on-pitch semi-circle drain side select gate technology","description":"A memory apparatus and method of operation are provided.
