    摘要: An operating voltage tuning method for a static random access memory is disclosed. The static random access memory receives a periphery voltage and a memory cell voltage. The steps of the method mentioned above are shown as follows. First, perform a shmoo test on the static random access memory to obtain a shmoo test plot and a minimum operating voltage. Compare the minimum operating voltage with a preset specification. Position a specification position point on the line which the periphery voltage is equal to the memory cell voltage in the shmoo test plot corresponding to the preset specification. Fix one of the memory cell voltage and the periphery voltage and gradually decrease the other to test the static random access memory and obtain a failure bits distribution. Finally, tune process parameters of the static random access memory according to the specification position point and the failure bits distribution.
