ACCELERATING DATA ACCESSING BY EXPLOITING FLASH MEMORY TECHNOLOGIES BY JING YANG A DISSERTATION SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY IN ELECTRICAL, COMPUTER AND BIOMEDICAL ENGINEERING UNIVERSITY OF RHODE ISLAND 2019 DOCTOR OF PHILOSOPHY DISSERTATION OF JING YANG APPROVED: Dissertation Committee: Major Professor Qing Yang Resit Sendag Ying Zhang Nasser H. Zawia DEAN OF THE GRADUATE SCHOOL UNIVERSITY OF RHODE ISLAND 2019 ABSTRACT Flash memory based SSD (solid state Drive) receives a lot of attention re- cently. SSD is a semiconductor device which provides great advantages in terms of high-speed random reads, low power consumption, compact size, and shock resis- tance. Traditional storage systems and algorithms are designed for hard disk drive (HDD), they do not work well on SSD because of SSD's asymmetric read/write performances and unavoidable internal activities, such as garbage collection (GC). There is a great need to optimize current storage systems and algorithms to accel- erate data access in SSD.
