An example method includes setting an alternate data cache (PDC1) to a logical AND of a secondary data cache (SDC) and a primary data cache (PDC0). The PDC1 is set to a logical AND of the PDC1 and a first result of a first sense operation. The PDC0 is set to a logical AND of the PDC0 and an inverse value of the PDC1. The PDC1 is set to a logical AND of the SDC and the PDC0. The PDC1 is set to a logical AND of the PDC1 and an inverse value of a second result of a second sense operation. The SDC is set to a logical AND of the SDC and the PDC0. The SDC is set to a logical OR of the SDC or the PDC0. The PDC0 is set to a logical AND of the PDC0 and a third result of a third sensing operation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and apparatus to preserve data of a solid state drive during a power loss event","description":"Methods, apparatus, systems and articles of manufacture to preserve data of a solid state drive during a power loss event are disclosed.
