In one approach, a voltage of a source side select gate transistor of a memory string is a decreasing function of the distance. In another approach, a magnitude or duration of an erase voltage at a source end of a memory string is an increasing function of the distance. Adjacent blocks can be arranged in subsets and treated as being at a common distance. In another approach, an additional erase pulse can be applied when the distance of the block exceeds a threshold. Other variables such as initial erase voltage and step size can also be adjusted as a function of distance."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Equalizing erase depth in different blocks of memory cells","description":"A memory device and associated techniques provide a uniform erase depth for different blocks of memory cells which are at different distances from pass gates of a voltage source.
