Abstract
A system includes a memory device and a processing device coupled to the memory device. The processing device can assign each of a plurality of superblocks to one of a plurality of groups. The processing device can monitor an order that each of the groups have been written to. The processing device can write data to a first block of a first superblock of a first of the plurality of groups.
Claims20
A system, comprising:
- a memory device;
- and
- a processing device coupled to the memory device, the processing device to perform operations comprising:
- assigning each of a plurality of superblocks to one of a plurality of groups for performance of a media management operation;
- monitoring an order that each of the plurality of groups have been written to;
- and
- writing data to a particular portion of a first superblock of a first of the plurality of groups based, at least in part, on the monitored order.

A method, comprising:
- assigning, at a processing device coupled to a memory device, each of a plurality of superblocks to one of a plurality of groups;
- monitoring, at the processing device, an order of writing to each of the plurality of groups;
- writing data to a first block of a first superblock of a first of the plurality of groups based, at least in part, on the monitored order;
- and
- erasing a second superblock of the first group concurrently with writing data to the first superblock of the first group.

An apparatus, comprising:
- a memory device comprising a plurality of superblocks;
- a processing device coupled to the memory device, the processing device to perform operations comprising:
- assigning, at a processing device coupled to a memory device, each of the plurality of superblocks to one of a plurality of groups;
- monitoring, at the processing device, an order of the groups based on an order that the groups were written to or a wear leveling characteristic;
- writing data to a particular superblock of one of the plurality of groups;
- erasing an additional superblock that is ordered subsequent to the particular superblock;
- and
- in response to receiving a message from a host, stopping the write to the particular superblock and continue a write to a second additional superblock previously erased and ordered between the particular superblock and the additional superblock.
