Abstract: Methods, systems, and devices for auto-calibration of error detection signals are described. An error may be injected into a data signal obtained from a memory array. After injecting the error into the data signal, the data signal may be applied to an error detection circuit of the memory array, where the error detection circuit may output an error signal for the data signal. The error signal may be delayed relative to a control signal by a first amount. A timing signal that controls the propagation of the error signal may be obtained based on delaying the control signal by a second amount. Based on a comparison of the error signal and the timing signal, a third amount for delaying the control signal may be determined.
