Abstract
Systems and methods for memory snapshots are disclosed. In particular, a memory device may include a volatile section and a backup persistent storage section. A snapshot manager circuit is positioned between a host control circuit or central processors. This snapshot manager circuit acts as a memory virtualization layer within the memory device and may use a redirect on write type command to put a snapshot of actively changed memory to a reserved memory area in the volatile section. A background function may copy the snapshots to the persistent storage section. Because the snapshot manager circuit is in the hardware memory access layers of the memory device, operation of the application is not interrupted or paused to access the specific memory sections. Further, snapshots are more readily available in the memory used by the host control circuit.
