发明名称 Semiconductor apparatus
摘要 A semiconductor apparatus including programmability that may allow a SSTL interface or LVTTL interface is provided. A reference configuration circuit (100) may provide a primary reference potential VREF0 and secondary reference potential VREF. Reference configuration circuit (100) may include a bond pad (PAD1), a reference potential generation circuit (1), a control circuit (50), a reference selection circuit (60), and a secondary reference potential generation circuit (70). During a wafer test mode, primary reference potential VREF0 and secondary reference potential VREF may be provided from a potential that may be applied to bond pad (PAD1).
