Four months after he joined Toshiba in 1971, Masuoka, who had just received a doctorate from Tohoku University, invented a type of memory known as SAMOS. After five years at Toshiba, he invented another type and was moved to the semiconductor production division, where he developed a 1-megabit DRAM.
