ABSTRACT:
A 3-state bidirectional buffer is directly connected with a data bus for a PROM, and it comprises a voltage dropping means which inputs the program power-supply voltage supplied to the PROM, then drops the input program power-supply voltage, and a bidirectional bus control means which controls the direction of the data bus on the basis of the program power-supply voltage dropped and the program input signal supplied to the PROM. A portable semiconductor storage device comprises such a 3-state bidirectional buffer inserted in a data bus for at least one PROM, and a buffer means through which a program input signal is supplied from an external circuit to the PROM.
