Abstract
The present disclosure generally relates to memory management during SGL fetching. When a data storage device is required to fetch an SGL from a host device, the data storage device cannot determine how much memory will be required to be allocated. The disclosure herein reduces the impact of the problem of under or over allocating memory and over-fetching, thereby reducing performance of the device during transfers. The disclosure provides guidance on how to implement an adaptive learning process based upon statistic collection of SGL fetches. By maintaining a table of statistics, the data storage device controller may learn and more closely predict an amount of memory to allocate for SGL fetching.
