Abstract
Aspects of a storage device are provided that requests L2P address translation data from an HMB for execution of an associated host command using a dynamically determined HMB transfer size. The storage device includes a volatile memory and a controller. The controller allocates, in the volatile memory, multiple memory locations for L2P address translation data from an HMB. The controller receives a command indicating a host data length, and transmits a request for a portion of the L2P address translation data stored in the HMB for the command. The HMB transfer size associated with the request may be based on the host data length of the associated host command, a quantity of free and contiguous memory locations available in the HMB read buffer, or a minimum between a size of the portion and a total size of the free and contiguous memory locations. Thus, HMB transfer latency may be reduced.
