Abstract
Apparatuses, systems, methods, and computer program products are disclosed for hybrid checkpointed memory. An extended memory module uses volatile memory of a host and a non-volatile memory medium as virtual memory for the host. A clone module clones data of a range of virtual memory in response to a checkpoint event for the range of virtual memory. A range of virtual memory may include data stored in a volatile memory and data stored in a non-volatile memory medium. A checkpoint module flushes dirty data of a range of virtual memory to a non-volatile memory medium in response to a checkpoint event. A hybrid checkpointed memory interface provides access to data of a range of virtual memory while dirty data is being flushed using data of a range of virtual memory, or using a clone of the data.
