Copies of the free block lists are maintained in the non-volatile memory. While allocating blocks from a first of the free block lists, the controller can update a second of the free block lists as part of a control sync operation preparing control data stored in non-volatile memory. This allows the memory system to operate in a non-blocking manner during the control sync. Once the second free block lists is prepared and the control sync completed, the second block can subsequently be used for block allocations and a control sync operation can be done to update the first block."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Block management in non-volatile memory system with non-blocking control sync system","description":"In a non-volatile memory system, the controller maintains in its volatile memory two free block lists for the assignment of memory circuit blocks when writing user and system data.
