  • Patent number: 11049536
    Abstract: A memory device includes a memory control unit and a write output clock device. The memory control unit is used to provide a write input clock and a first control value. The write output clock device produces a plurality of internal clocks based on the write input clock, and selects a target internal clock from the plurality of internal clocks, and further delays the target internal clock to become a write output clock to a memory unit based on the first control value. The memory unit produces a data signal based on the write output clock. The memory control unit identifies whether the write output clock meets the time-sequence requirements of the memory unit. If the time-sequence requirements are not met, the memory control unit changes the first control value and/or changes the selected target internal clock to change the write output clock.
