Abstract :
This paper describes the total dose radiation performance of CMOS/SOI 4 Kb SRAMs fabricated in a radiation hardened partially depleted SOI CMOS technology. The SRAM adopts 1 K×4 architecture. It achieves a fast access time 30 ns and chip size 3.6 mm×3.84 mm. Memory functionality does well after a total dose irradiation up to 5×105 rad(Si) under 3 V power supply. This meets the needs in military and aerospace fields. It is the first time that the radiation effects on SOI VLSI were investigated in China
