Abstract :
This paper describes the vertical and horizontal packaging method for Resistive RAM (ReRAM)/NAND flash hybrid SSD. The parasitic effects of vertical and horizontal connections for 3D-hybrid SSD are investigated. The result shows 128 NAND flash memory chips can be stacked considering with VPGM and VPASS. In addition, only 4-chip is allowed between ReRAM and the boost converter due to TSV´s parasitic resistance. Also, the length of the horizontal on-interposer wire must be kept less than 3 mm.
