In one approach, a vertical three-dimensional cross-point memory device uses digit line decoders that include, on the digit line side of memory cells, a current limiter and sensing circuit configured to control program current in either of positive or negative program polarities, as selected by a controller. Two current limiters are each used on the digit line side of each memory cell. A negative polarity current limiter is used for pull-up, and a positive polarity current limiter is used for pull-down. A negative polarity sensing circuit is used between the respective digit line decoder and a positive supply voltage. A positive polarity sensing circuit is used between the respective digit line decoder and a negative supply voltage. The current limiter and sensing circuit pair of the same polarity is coupled to each digit line decoder based on the selected program polarity."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Program current controller and sense circuit for cross-point memory devices","description":"Systems, methods, and apparatus related to memory devices.
