Abstract
In an information processing system, a wait state signal is inserted into a RDY signal, according to which data are transmitted through memory and I/O buses. A CPU controls the number of the wait state signal to adjust the difference of the transfer speeds of the memory and I/O buses. An MCU (Memory Controller Unit) includes configuration and refresh timer registers for specifying the configuration and the refresh cycle of a memory to be accessed.
