The NSF has awarded Dr. Biswajit Ray a five-year, $650,000 Faculty Early Career Development Program (CAREER) award to pursue his research. Ray and his team of doctoral students and graduate researchers are working on the project now.
Solid-state drives are fast and powerful storage drives for computer data. Ray’s research aims to develop storage management techniques that can double their lifetimes, UAH said this week.
SSD’s store data in flash memories, and the technology in those memories is also rapidly evolving. “I find recent technological developments very exciting,” Ray said in the university’s release. “Manufacturers are releasing chips that can hold over 1.33 terabits of information, and these chips are three-dimensional structures with storage cells placed in multiple layers.”
Issues with the new drives include energy efficiency, security and privacy, Ray said.
“The project addresses these issues through intelligent memory management techniques which can be implemented through software-based solutions in the storage firmware,” he said. “We will evaluate these techniques on state-of-the-art-flash memory chips.”
What could such storage allow in the future? Better predictive analytics and artificial intelligence in low-end computers capable of operating in “extreme environments, such as nuclear environments and space, where flash drives are attractive due to their light weight, high density and small size,” the announcement said.
Ray said his team’s work will allow system designers to create new memory management functions “that go beyond the algorithmic techniques” to assess and optimize memory performance. Two companies are already interested.
“I have a partnership with Western Digital and Infineon Technologies,” Ray said. “They are very much excited on the outcome of the project. They will provide technical mentorship and related resources for the success of the project.”
The three doctoral students working in Ray’s Hardware Reliability and Security Laboratory are Matchima Buddhanoy, Md Raquibuzzaman and Umeshwarnath Surendranathan.
