WebThe decreasing raw reliability of flash memory NAND chips has drastically impacted the lifetime of commercial SSDs. For example, older SLC NAND-flash-based SSDs were able to withstand 150 000 P/E cycles (writes) to each flash cell, but contemporary 1x-nm (i.e., 15–19 nm) process-based SSDs consisting of MLC NAND flash can sustain only 3000 WebSemiconductor flash memory is an indispensable component of modern electronic systems. The minimum feature size of an individual CMOSFET has shrunk to 15nm with an equivalent gate oxide thickness (EOT) of 0.8nm in 2001. However, semiconductor flash memory scaling is far behind CMOS logic device scaling.
