19nm & 20nm SSDs Arrive!

Toshiba 19nm vs. IMFT 20nm NAND Processes (Courtesey Techinsights and Toshiba)SSD-watchers have expressed some concern over the last few years that  SSDs cannot be manufactured using advanced NAND flash process geometries.  This is because these parts have lower endurance and a larger number of bit errors than NAND made using less-advanced processes – the tighter the process, the shorter the flash’s life, and the more errors it will have.

Fortunately these concerns seem to be Continue reading
