Abstract: Memory subsystem error management enables dynamically changing lockstep partnerships. A memory subsystem has a lockstep partnership relationship between a first memory portion and a second memory portion to spread error correction over the pair of memory resources. The lockstep partnership can be preconfigured. In response to detecting a hard error in the lockstep partnership, the memory subsystem can cancel or reverse the lockstep partnership between the first memory portion and the second memory portion and create or set a new lockstep partnership. The detected error can be a second hard error in the lockstep partnership. The memory subsystem can create new lockstep partnerships between the first memory portion and a third memory portion as lockstep partners and between the second memory portion and a fourth memory portion as lockstep partners. The memory subsystem can also be configured to change the granularity of the lockstep partnership when changing partnerships.

Abstract translation: 内存子系统错误管理可实现动态更改的锁步合作伙伴关系。 存储器子系统具有在第一存储器部分和第二存储器部分之间的锁步合作关系，以在所述一对存储器资源上扩展纠错。 锁定合作伙伴关系可以预先配置。 响应于检测锁步伙伴关系中的硬错误，存储器子系统可以取消或反转第一存储器部分和第二存储器部分之间的锁步合作关系，并创建或设置新的锁步伙伴关系。 检测到的错误可能是锁步伙伴关系中的第二个硬错误。 存储器子系统可以在第一存储器部分和第三存储器部分之间创建新的锁步合作关系，作为锁步伙伴，并且在第二存储器部分和作为锁步伙伴的第四存储器部分之间。 内存子系统也可以配置为在更改合作伙伴关系时更改锁步伙伴关系的粒度。
