A signal output adjustment circuit includes a decoder which decodes command data from a memory, a control register in which control data corresponding to first command data is set when the decoder determines that the command data is the first command data, a buffer in which the control data corresponding to second command data is stored when the decoder determines that the command data is the second command data, and an output adjustment circuit which reads the control data stored in the buffer and outputs the control data in synchronization with a data fetch signal, based on a value set in the control register. At least one of permission/rejection of inversion output of the data fetch signal and output timing of the data fetch signal is set based on the value set in the control register.
