Samsung patents storage method that moves data between memory zones
Samsung describes a way for a storage controller to split memory into separate zones. When data is written, the system can move it from one zone to another to manage how the memory is used.
In the filing’s own words
A storage device includes a non-volatile memory including a plurality of blocks, and a storage controller configured to divide the plurality of blocks into a plurality of zones, determine a first zone of the plurality of zones corresponding to a logical address received from a host, based on a value of the logical address, map the logical address to a physical address corresponding to a first block in the first zone, and replace at least one of the logical address or the first block with a logical address or a block of a second zone of the plurality of zones. The second zone is different from the first zone.
What exactly they claim (claim 1)
1. A storage device comprising: a non-volatile memory including a plurality of blocks; and a storage controller configured to divide the plurality of blocks into a plurality of zones, determine a first zone of the plurality of zones corresponding to a logical address received from a host, based on a bit value of the logical address, map the logical address to a physical address corresponding to a first block in the first zone, and replace at least one of the logical address or the first block with a logical address or a block of a second zone of the plurality of zones, the second zone different from the first zone.
