Direct hinting for a memory device

摘要

A data storage area of a data storage device can be used to communicate information between the data storage device and an external device or software. In some examples, configuration data stored within the data storage area can be used to determine a subset of data to copy or move from a first data storage medium to a second data storage medium. The data storage area can be a unique partition and the data storage device can locate partition information to determine a location of the partition. The data storage device can then use the partition to store data for two-way communication between the data storage device and an external system, device, or software.

1. An apparatus comprising:
a first memory; a second memory; a controller coupled to the first memory and the second memory, the controller configured to:
receive a write command from a host including first data to be stored at a first data storage location of the first memory,
the first data including an indicator identifying other data to be transferred from the first memory to the second memory,the first data storage location is a direct hint partition that is a partition reserved to store the first data;store the first data to the direct hint partition;read the indicator from the direct hint partition to receive instruction from the host to transfer the other data to the second memory; andstore the other data in the second memory based on the indicator in the first data.
