ABSTRACT:
A micro-computer system using a DRAM can refresh the DRAM in a certain interval cycle to maintain the memory contents or refresh the DRAM memory even when the system is set into the standby mode and the clock generator has stopped providing clock timing signals to the memory refreshing circuit. Accordingly, the DRAM memory is refreshed by automatically changing from the interval refresh mode to the self refresh mode when the system operation changes from the normal operation to the standby operation, thus achieving low system power consumption.
