ABSTRACT:
A portable semiconductor memory unit comprises a semiconductor memory requiring different voltages for reading and writing. A single supply voltage is supplied to the portable semiconductor memory unit from an external terminal equipment and transformed by a transforming circuit provided in the portable semiconductor memory unit with necessity to be applied to the semiconductor memory. Thus, the terminal equipment does not need to be installed with a dedicated voltage supply circuit for generating different level voltages.
