摘要：
This disclosure is related to systems and methods for selective metadata storage in a system having multiple memories. In one example, a device may include a control circuit configured to selectively store a metadata base map in a first memory or a second memory. The metadata base map may include information to determine a physical memory address from a logical block address. The control circuit may also be configured to store metadata updates separately from the metadata base map. The metadata updates may comprise changes to the metadata base map. The control circuit may also be configured to selectively store the metadata updates in the first memory or the second memory based on characteristics of the device.
