Abstract:
In a device including a programmable circuit, the programmable circuit is connected to a non-volatile memory in which configuration information is stored, and another memory having a faster reading speed than the non-volatile memory, and the programmable circuit includes a configuration memory control circuit, and a signal line group for performing reading with respect to the other memory such as a volatile memory and an embedded memory from the non-volatile memory by the configuration memory control circuit, and copies a part of circuit configuration information which is required to be subjected to fast restoration from failure into the other memory.
