Methods, systems, and devices for efficient error signaling by memory are described. When executing a read operation, a memory device may perform an error control operation to detect errors in data associated with the read operation and transmit signaling indicating the data. The memory device may transmit signaling indicating a first or second value of an indicator of a combination error: the first value indicating that an error was detected in the data during the error control operation or a non-driven condition for transmitting the signaling indicating the data, and the second value indicating that no errors were detected in the data during the error control operation and that the read operation has been executed. The memory device may additionally store a value in a register indicating whether an indicated combination error corresponds to errors being detected in the data, a non-driven condition, or both.
