Abstract
In a semiconductor memory device, a plurality of output buffers, one for each output data bit, are powered by an internal voltage control circuit so as to provide high speed operation yet minimize power consumption. The internal voltage control circuit inclues multiple internal voltage generators. Responsive to the number of output buffers in use during a read operation, one or more of the voltage generators are activated to power the output buffers. Additionally, the current capacity of each of the individual voltage generators is controlled responsive to the number of output buffers in use during the read operation, so that bandwidth of the memory device is maximized but power is not wasted.
