  • Strobe gating adaption and training in a memory controller
    Patent number: 9514420
    Abstract: A memory controller includes a differential receiver circuitry to receive a differential data strobe signal pair and to generate a first data strobe signal based on the differential data strobe signal pair. The differential data strobe signal pair comprises a first signal and a second signal. The memory controller also includes a single ended receiver circuitry to receive the first signal of the differential data strobe signal pair and to generate a second data strobe signal based on the first signal of the differential data strobe signal pair. The memory controller further includes circuitry to generate a gating signal for gating the first data strobe signal, the circuitry generating the gating signal based on the second data strobe signal.
