4-Times Faster Rising V_PASS (10V), 15% Lower Power V_PGM (20V),
Wide Output Voltage Range Voltage Generator System
for 4-Times Faster 3D-integrated Solid-State Drives

 

Abstract

A wide output voltage range from 10V to 20V voltage generator system is proposed for 3D-SSDs. The circuits are fabricated with the smart mix and match of the standard CMOS, low voltage and high voltage NAND flash memory technologies. The measured rising time for VPASS, 10V, is four times shorter. The power consumption for VPGM, 20V, decreases by 15%. As a result, the SSD performance increases by 4 times.
