The Company noted this represents a six year record highfor its second quarter revenue.ChipMOS continues to benefit from growth in its memory business,led by DRAM and NOR flash demand in support of cloud-based storage services and applications,ongoing 5G network buildouts worldwide,and higher demand from the gaming market and in support of increased work and school from home needs. Within its DRAM business,commodity DRAM was stronger in the second quarter 2020 than niche DRAM. DDIC revenue was impacted by continued softness in smartphones and TVs,both of which are positioned for a potential rebound in growth in the second half of 2020 due to rationalized inventory in the supply chain along with an expected demand recovery.
