Power semiconductors and semiconductor memory comparison

Power semiconductors are vulnerable country's overall competitiveness in memory semiconductors compared to the structure without the absolute leader in the production of many kinds

Division Function and role Market Status
Muscle Power Semiconductor High voltage, And precisely the power needed to control a large current Provide a stable supply of semiconductor
(Ex : Motor Drive)		 World Markets about 344Billion$
Diversified production subject
Leading international companies
(World 20My top None Nationality company)
Brain Memory Chip(DRAM) Information into a digital signal Storing semiconductor
(Ex: PC or Smartphone Storage)		 World Markets about 1302Billion$
Small species massive production subject
Leading domestic companies
(Samsung, SKHynix 62% occupancy)
