Methods and apparatus for passing information to a host system to suggest logical locations to allocate to a file

摘要

Methods and apparatus for passing information to a host system to suggest logical locations to allocate to a file are disclosed. Generally, when a host system determines a need to allocate a logical location to a file, the host system sends a non-data command to a memory system. In response, the memory system sends information to the host system that includes one or more logical locations to allocate to the file. By suggesting one or more logical locations to allocate to a file, the memory system may reduce a number of data consolidation or garbage collection operations that will need to be performed in the future, thereby improving performance of the memory system.

1. A re-programmable non-volatile mass storage system comprising:
a non-volatile memory; a LBA interface configured to couple the re-programmable non-volatile mass storage system to a host system; and a controller in communication with the non-volatile memory and the LBA interface, the controller configured to:
receive over the LBA interface a non-data command from the host system, where the non-data command does not result in a logical data transfer from the host system to the mass storage system; andsend information to the host system over the LBA interface in response to the non-data command, the information comprising one or more logical locations that the mass storage system recommends the host system allocate to a file.
