In accordance with some embodiments, a memory device has a word memory array formed of non-volatile resistive sense memory (RSM) cells, a first index array formed of volatile content addressable memory (CAM) cells, and a second index array formed of non-volatile RSM cells. The memory device is configured to output word data from the word memory array during a data retrieval operation when input request data matches tag data stored in the first index array, and to copy tag data stored in the second index array to the first index array during a device reinitialization operation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Non-volatile memory with hybrid index tag array","description":"Various embodiments of the present invention are generally directed to an apparatus and associated method for a non-volatile memory with a hybrid index tag array.
