Abstract: A logical-to-physical (L2P) address mapping table is maintained, wherein a plurality of sections of the L2P address mapping table is cached in a volatile memory device. A journal entry count is maintained reflecting a number of L2P journal entries associated with an L2P journal. It is determined that the journal entry count satisfies a first threshold criterion. In response to determining that the journal entry count satisfies the first threshold criterion, a writing of the L2P journal to a non-volatile memory device is triggered. A written journal count reflecting a number of L2P journals written to the non-volatile memory device is maintained. In response to determining that the written journal count satisfies a second threshold criterion, a first section of the plurality of sections of the L2P address mapping table is identified. The first section of the L2P address mapping table is written to the non-volatile memory device.

Abstract: A logical-to-physical (L2P) table is maintained, wherein a plurality of sections of the L2P table is cached in a volatile memory device. A total dirty count for the L2P table is maintained, wherein the total dirty count reflects a total number of updates to the L2P table. Respective section dirty counts for the plurality of sections are maintained, wherein each respective section dirty count reflects a total number of updates to a corresponding section. It is determined that the total dirty count for the L2P table satisfies a threshold criterion. In response to determining that the total dirty count for the L2P table satisfies the threshold criterion, a first section of the plurality of sections is identified based on the respective section dirty counts. The first section of the L2P table is written to a non-volatile memory device.

Abstract: A total count for an address mapping table is maintained, wherein the total count reflects a total number of updates to the address mapping table, and wherein the address mapping table comprises a plurality of sections. Respective section counts for the plurality of sections are maintained, wherein each respective section count reflects a total number of updates to a corresponding section. It is determined that the total count for the address mapping table satisfies a threshold criterion. A first section of the plurality of sections with a highest section count is identified based on the respective section counts. The first section of the address mapping table is written to a non-volatile memory device.
