Abstract
A method for reducing the current consumption of a reference voltage circuit while a synchronous DRAM is in standby power-down mode is provided. The reference voltage is stored on a capacitor within the DRAM circuit. The reference voltage circuit is selectively disconnected from, and reconnected to the Vref-node at predetermined time intervals during a power down mode, in order to ensure leakage compensation. When the power down mode exceeds a predetermined time, the reference voltage circuit is disabled to further reduce the current consumption.
