Samsung patents storage method that moves data between zones to speed up writes
Samsung describes a storage device that uses a shared buffer in a reserved memory area to temporarily hold incoming data. A controller then moves this data to specific storage zones based on its characteristics, aiming to improve how the device handles write operations.
In the filing’s own words
A storage device, including a nonvolatile memory device including a plurality of memory cells forming a user area and a reserved area; and a controller configured to perform a write operation on at least one write unit included in the plurality of memory cells, and to perform an erase operation on at least one erase unit included in the plurality of memory cells, wherein the controller includes an internal buffer, wherein the controller is configured to: perform a backup operation by writing first data stored in the internal buffer in a backup erase unit included in the reserved area, and after performing the backup operation adjust a buffering unit of the internal buffer to correspond to a cell type of the backup erase unit.
What exactly they claim (claim 1)
1. A storage device comprising: a nonvolatile memory device comprising a plurality of memory cells forming a user area and a reserved area; and a controller configured to: allocate a plurality of zones to a storage space of the nonvolatile memory device, based on receiving first data corresponding to a first zone from among the plurality of zones from an external host device, write the first data in a shared write boost buffer included in the reserved area of the nonvolatile memory device, based on receiving second data corresponding to a second zone from among the plurality of zones from the external host device, write the second data in the shared write boost buffer, select the first zone based on a first feature corresponding to the first zone and a second feature corresponding to the second zone, and based on selecting the first zone, migrate the first data from the shared write boost buffer to the first zone.
