Large Data Read Prefetch for Low-Latency Storage Transfer

The patent segments large data transfer operations into multiple atomic unit reads that can be executed in parallel. The host device divides a large read request into multiple smaller sub-requests, each targeting a specific atomic unit (page or block) in the storage device. These segmented requests are then processed simultaneously through multiple I/O channels, resolving the contradiction by maintaining atomic unit reliability while achieving efficient large data transfer through parallel execution of segmented operations.

The patent implements preliminary action by pre-fetching data blocks into the storage device's cache memory before the host actually needs them. The storage device proactively reads data blocks that are likely to be accessed soon and stores them in cache, so when the host issues read commands, the data is already available or can be quickly retrieved. This eliminates wait time and reduces latency for large data transfers while maintaining the atomic unit read command structure.

The patent segments the sequential read process into parallel operations across multiple I/O channels. Instead of issuing multiple single-unit read commands sequentially through one channel, the host divides the read request into segments and sends them simultaneously through multiple independent channels. This segmentation maintains data transfer accuracy for each atomic unit while dramatically reducing total power consumption by eliminating the sequential execution overhead and utilizing parallel processing capabilities of the storage device.

The patent merges multiple atomic unit read operations into a single coordinated parallel execution framework. Multiple I/O channels that would otherwise operate independently are merged into a unified parallel read operation, where multiple atomic units are read simultaneously through different channels. This combining approach maintains the reliability of individual atomic reads while reducing overall power consumption by executing operations in parallel rather than sequentially, leveraging the storage device's ability to handle multiple concurrent operations.

The patent segments large data transfer operations into multiple atomic unit reads that can be executed in parallel through multiple I/O channels. This segmentation allows the system to bypass the limitation of small cache size by processing data in smaller atomic units that fit within the constrained cache, while achieving large data transfer efficiency through parallel execution. The host device divides large read requests into segments, each manageable within the limited cache capacity, and processes them simultaneously rather than sequentially.

The patent implements preliminary action by pre-fetching data blocks into the storage device's limited cache memory before the host needs them. The storage device proactively reads and caches data blocks that are likely to be accessed soon, maximizing the utilization of the constrained cache space. This pre-fetching mechanism allows mobile devices with small caches to achieve high productivity for large data transfers by having data ready in cache before actual read operations, eliminating wait time and improving overall transfer efficiency despite the small cache volume.
