Abstract

We present a flash memory system with low cost and high performance for solid-state disk. The proposed flash system is constructed as a SLC with hot blocks and a MLC with cold blocks. Either the SLC or the MLC is selectively accessed on the basis of a position bit in a mapping table. Our results show that the system enables the SLC size to be reduced by about 80% relative to a conventional SLC while maintaining similar performance. And also, our system can improve a performance by above 60% comparing with a conventional MLC.
