Abstract
A receiving circuit that receives differential data strobe signals between a controller and a memory, the receiving circuit includes: a first receiver that compares one of the differential data strobe signals to the other, output a high logic value when the one of the differential data strobe signals is higher than the other, and output a low logic value when the one is lower than the other; a second receiver that compares one of the differential data strobe signals to a strobe reference voltage, output a high logic value when the one of the differential data strobe signals is higher than the strobe reference voltage, and output a low logic value when the one of the differential data strobe signals is lower than the strobe reference voltage; and a determination circuit that outputs a logical OR of an output of the first receiver and an output of the second receiver.
