Solid State Disc (SSD)

Solid State Drives (SSD) are rapidly become the storage medium of choice. They offer a number of distinct advantages over mechanical hard disk drives (HDD), including faster boot-up times and data movement. In addition they tend to be smaller and more efficient. Efficient PMUs can decrease erroneous rewrites by providing more stable voltage rails for the NAND and FLASH memory cells

Design considerations

MOSFETs used as loadswitches for power sequencing - e.g. for NAND, Flash and I/Os

Low power comsumption and therefore high-efficiency devices needed
