  • Publication number: 20230385209
    Abstract: A method of operating a storage device includes receiving a first bit sequence including a request for changing a data rate from a host according to a first data rate through an input signal pin; sending a second bit sequence including a response to the request for changing a data rate to the host at the first data rate through an output signal pin; and changing the data rate to a second data rate according to whether a tail-of-burst (TOB) indicating an end of the second bit sequence is output.

  • Patent number: 11726677
    Abstract: Disclosed is a storage device which includes an interface circuit that exchanges data with a host device, and a power management unit that supplies a power to the interface circuit. The interface circuit includes a first input terminal receiving a first signal from the host device, a second input terminal receiving a second signal complementary to the first signal from the host device, a receive module processing the first signal and the second signal, a squelch circuit detecting levels of the first signal and the second signal, and a reference clock detector detecting whether a reference clock for operating the storage device is received. The power management unit selectively supplies a power to the squelch circuit based on a result of the detection by the reference clock detector.
