US Patent 11416263 Boosted boot procedure by background re-arrangement of read patterns

A data storage device includes a memory device and a controller coupled to the memory device. During a boot operation, the controller is configured to determine whether the boot is a device boot or a host boot. The controller includes a boot optimization unit. The boot optimization unit or the controller is configured to collect statistics of the fetched data, predict the data to be fetched next, and speculatively fetch the data. The controller further includes a rearrangement unit. The controller or the rearrangement unit is configured to rearrange data in the memory device based on the collect statistics of the fetched data so that the next boot operation is more optimized than the current boot operation.
