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.
