Abstract
Characteristics of each transistor in a semiconductor device including a transistor of a memory cell are measured by an ASV monitoring circuit, a power supply voltage supplied to the semiconductor device is determined based on the measured characteristics of the transistor, a data read-out speed of the memory cell under the determined power supply voltage supplied is measured while changing a signal level of a word line by an SRAM word line monitoring circuit, the signal level of the word line is determined by comparing the measured data read-out speed of the memory cell and a specification range of the memory cell, and the signal level of the word line is appropriately set at the power supply voltage applied by the ASV.
