Abstract: PURPOSE:To prevent a semiconductor memory from causing an alpha-ray software error by providing capacity means for increasing the substantial gate capacity values of a pair of enhancement type driving MESFETs in a flip-flop circuit which contains the pair of enhancement type driving MESFETs having gates and drains coupled in a crossing manner. CONSTITUTION:Schottky diodes D1, D2 are provided between the gates and the drains of driving MESFETs Q1, Q2 which form a memory cell. When the MESFETQ1 is, for example, OFF and the MESFETQ2 is ON, the drain of the MESFETQ1 is at a high level such as approx. 0.6V, and the drain of the MESFETQ2 is at a low level such as approx. ground potential Vss of the circuit. The diode D1 is reversely biased to act substantially as a capacitor. Thus, even if carrier is generated by emitting, for example, an alpha-ray to the gate of the MESFETQ1, the inversion of the Q1 can be prevented by the charge stored by the reverse bias of the diode D1.
