Methods, systems, and devices related to generating, by a pseudorandom binary sequence (PRBS) generator of a memory module, a PRBS comprising a first plurality of bits corresponding to a plurality of cycles of a clock signal of the memory module subsequent to a current cycle of the clock signal. Generation of the PRBS can be based on an intermediate PRBS comprising a second plurality of bits corresponding to the current cycle of the clock signal. During each respective cycle of the clock signal, a respective subset of the PRBS can be communicated from the PRBS generator to a memory device of the memory module. Each respective subset of the PRBS comprises a quantity of bits based on a frequency of a data strobe signal of the memory device relative to a frequency of the clock signal.
