A single event transient-resistant reinforced register suitable for an SRAM type FPGA for aerospace is disclosed. A register unit performs processing on a SET pulse by a novel delay unit to make the register have high SET capability. The reinforced register consists of four parts of an internal data and clock generation circuit, a master latch, a slave latch and an output buffer. The internal data and clock generation circuit uses an NAND gate and an NOR gate to form a delay chain for processing the SET pulse; and the master latch and the slave latch use a latch unit based on a DICE (Dual Interlocked storage CEll) structure. The reinforced register, by using inherent characteristics of a DICE unit, only uses one delay chain to shield the SET pulses in a clock terminal CLK and a data terminal D at the same time. Compared with a conventional SET reinforced register, the reinforced register provided by the present invention has fewer delay units, so that the overall area of the reinforced register is smaller than that of the conventional reinforced register.
