The Ministry of Education, Science and Technology said Monday that a Korean research team led by Prof. Choi Yang-kyu of the Korea Advanced Institute of Science and Technology has developed a next-generation fusion memory chip called United RAM (URAM) that incorporates the advantages of both flash memory and DRAM.
Flash memory holds data even when the power is switched off, making it fit for use in portable electronic devices like camcorders and mobile phones. But it is not useful for high-capacity data like video clips due to its low data-processing speed. This is why the team added DRAM technology, which boasts high data-processing speeds, to URAM. It is expected to enable seamless delivery of high-density video content in portable electronic devices.
In addition, it will be possible to mass-produce the new fusion chips because the existing design process of memory chips can be used for it. "We expect URAM will help integrate the separate markets of personal computers and portable electronics devices because it can be used to manufacture both, whereas DRAM is used only for personal computers and flash memory for portable electronics devices," Prof. Choi said.
