  • CIRCUITS AND METHODS FOR DQS AUTOGATING
    Publication number: 20170270995
    Abstract: In one aspect, a method includes receiving a differential strobe signal including first and second components; buffering, by a first buffer, both the first and second components; and buffering, by a second buffer, the first component. The method includes receiving, by a control logic block, the output of the second buffer. The method includes, after a period when the values of both the first and second components are at a first logic state, but before receiving a burst of clock edges in the differential strobe signal, detecting a transition in the first component from the first logic state to a second logic state, and in response to the detected transition, asserting an enable signal. The method further includes receiving, by a gating logic block, the enable signal and the output of the first buffer, and, when the enable signal is asserted, un-gating the output of the first buffer.
