ABSTRACT:
A device capable of controlling a supply voltage and a supply frequency using information of a manufacturing process variation includes a data storage device storing data indicating performance of the device, a decoder decoding the data stored in the data storage device and outputting decoded data, and a frequency control block outputting a frequency controlled clock signal in response to the decoded data output from the decoder. The device further includes a voltage control block outputting a level controlled supply voltage in response to the decoded data. The voltage control block outputs a body bias control voltage controlling a body bias voltage of at least one of a plurality of transistors embodied in the semiconductor device in response to the decoded data. The performance is operational speed of the device or leakage current of the semiconductor device.
