Fast boot in hybrid drives

摘要

The disclosure is related systems and method for improved boot and resume from hibernate times in hybrid drives. In one embodiment, a device may comprise an interface circuit to communicate with a host device, a first nonvolatile data storage medium, and a controller configured to monitor the interface circuit for a trigger event and pin data associated with read requests to the first nonvolatile data storage medium during a first specific duration in response to the trigger event. Another embodiment may be a method comprising receiving a trigger event, monitoring a duration since the trigger event, retrieving data from a nonvolatile cache memory, retrieving data from a disc memory when the data is not in the nonvolatile cache memory, and pinning the data retrieved from the disc memory to the nonvolatile cache memory.

1. A device comprising:
an interface circuit to communicate with a host device; a first nonvolatile data storage medium; a controller configured to:
monitor the interface circuit for a trigger event;during a first specific duration in response to the trigger event:
pin data associated with read requests to the first nonvolatile data storage medium;monitor the interface circuit for a pre-determined command indicating a boot sequence;continue to pin data associated with the read requests to the first nonvolatile data storage medium during a second specific duration when the pre-determined command is received during the first specific duration; andstop pinning data associated with the read requests to the first nonvolatile data storage medium when the pre-determined command is not received during the first specific duration.
