Zusammenfassung:An apparatus, system, and method for improved memory control are provided. A circuit can include controller circuitry configured to determine, based on a speed of silicon of a memory, a read strobe code that adjusts a data clock to account for a difference between a reference clock and a data clock in terms of a number of unit intervals (UIs) and a read strobe code, a receive delay locked loop to receive the difference and delay the data clock by the number of UI and read strobe codes resulting in a delayed data clock, and a sampling amplifier to sample data from the memory based on the delayed data clock.
