Samsung patents storage drive that auto-tunes its speed to the computer
This filing describes a storage device that measures the timing signal sent from a computer to determine its exact frequency. It uses this measurement to automatically set the correct speed for the connection when the drive first turns on.
In the filing’s own words
A storage device and a storage system including the same are provided. The storage device includes a reference clock pin configured to receive a reference clock signal from a host, a reference clock frequency determination circuitry configured to determine a reference clock frequency from the reference clock signal received through the reference clock pin, and a device controller circuitry configured to perform a high speed mode link startup between the host and the storage device according to the reference clock frequency.
What exactly they claim (claim 1)
1. A storage device comprising: a nonvolatile memory; a controller coupled to the nonvolatile memory; and an interconnect circuitry coupled to the controller, wherein the interconnect circuitry comprises: a reference clock counter configured to generate a reference clock count value by counting a number of clocks in a reference clock signal received from a host; and a system clock counter configured to generate a system clock count value by counting a number of clocks in a system clock signal of the storage device, wherein the storage device is configured to: determine a reference clock frequency based on a ratio of the reference clock count value and the system clock count value, and perform a link startup process with the host according to the reference clock frequency, during initialization and/or booting of the storage device.
