Abstract:
First to N-th selection signals each instantaneously having a first logic level when representing selection and a second logic level when representing deselection are generated based on selection designation data. The first to N-th selection signals are individually latched, and first to N-th delayed selection signals are generated by individually delaying the first to N-th selection signals by a greater amount of delay when the latched selection signals transition from the first logic level to the second logic level than when the latched selection signals transition from the second logic level to the first logic level. A delayed data signal is selected corresponding to a delayed selection signal having the first logic level among the first to N-th delayed selection signals. The selected delayed data signal is output.
