US Patent 11403011 Host memory buffer allocation management
Aspects of a storage device including a memory and a controller are provided. The memory includes a volatile memory. The controller can determine that at least a portion in the volatile memory is a reusable region based on a host memory allocation from a host device. The controller also can calculate a size of the reusable region in the volatile memory. The controller also can perform one or more storage device operations in the reusable region of the volatile memory in response to the host memory allocation based on the calculated size of the reusable region. Thus, the controller may provide smart handling of host memory buffer allocation, thereby improving storage device read performance.
