A High Cost-Performance and Reliable 3-Level MLC NAND Flash Memory Using Virtual Page Cell Architecture

A new high cost-performance NAND Flash memory using 3-level MLC and virtual page cell architecture has been proposed. It provides 20% die size saving and 3 times fast program speed compared to conventional SLC and MLC, respectively. The proposed method can be a good choice of the market demanding both low cost and high performance as well as high reliability
