Data generation circuit, memory, and determination method of data generation circuit

The invention provides a data generation circuit, a memory and a determination method of the data generation circuit, and relates to the technical field of semiconductors. The data generation circuit comprises a first generation circuit corresponding to a first bit, the first generation circuit comprises a first input end and a first output end, the first input end is used for receiving a first selection signal, and when the first selection signal is a first level, the first output end is used for outputting a second selection signal; and when the first selection signal is the first level, outputting a first level as a value of a first bit in the first data group through the first output end, or when the first selection signal is the second level, outputting a second level as a value of a first bit in the second data group through the first output end. It can be seen that the data generation circuit can multiplex the first generation circuit for the first data set and the second data set so as to generate the
