摘要
A semiconductor device having an internal circuit (5) comprises a program circuit (1) for programming a PROM (2), a discrimination circuit (3) for discriminating the contents of the PROM (2), and a specific mode starting circuit (4) for operating the internal circuit (5) in a specific mode when a specific mode starting signal is output from the discrimination circuit (3). Consequently, the operating mode of semiconductor device can be established and changed by programming and re-programming the PROM (2) without the need for special additional equipment.
