ABSTRACT:
A device includes an electrically programmable semiconductor integrated circuit or circuits, such as a Field Programmable Gate Array. Each circuit comprises a plurality of fundamental sections connected to a plurality of signal lines, wherein each fundamental section is permitted to carry out both operation in a logical operation mode for performing a logical operation using signals delivered from the signal lines and operation in a wiring formation mode for carrying out setting of connecting states between the respective signal lines, whereby the semiconductor integrated circuit is operable in any operation mode arbitrarily selected. The fundamental section may be of a structure capable of performing a sequential logical operation as the logical operation mode. In this case, at least one of the memories of the memory section corresponds to a latch memory.
