Samsung patents SSD data transfer method using consecutive PRP lists

Samsung has filed a patent for a method that improves how data is moved to and from Solid State Drives (SSDs). The system uses a specific bit in a command to tell the drive whether the data locations are next to each other or scattered, allowing the drive to process the transfer more efficiently.

Why it mattersThis is a routine technical improvement that helps computer storage drives handle data commands more effectively, potentially reducing the workload on the drive's controller.

In the filing’s own words

The present disclosure provides method and apparatus for performing data transfer in an SSD. The method includes configuring, by a host, a designated bit in a Non-Volatile Memory Express (NVMe) command to indicate a contiguous state or a non-contiguous state of a first Physical Region Page (PRP) list and a second PRP list among a plurality of PRP lists; and transmitting, by the host, the NVMe command for a controller of the SSD to perform data transfer in the SSD based on the designated bit.

What exactly they claim (claim 1)

1. A method for data transfer to and from a Solid State Drive (SSD), the method being executed by one or more processors, the method comprising: configuring, by a host, a designated bit in a Non-Volatile Memory Express (NVMe) command to indicate a contiguous state or a non-contiguous state of a first Physical Region Page (PRP) list and a second PRP list among a plurality of PRP lists; and transmitting, by the host, the NVMe command for a controller of the SSD to perform data transfer in the SSD based on the designated bit.
