7.1 A low-power 64Gb MLC NAND-flash memory in 15nm CMOS technology

Abstract

The demand for high-throughput NAND Flash memory systems for mobile applications such as smart phones, tablets, and laptop PCs with solid-state drives (SSDs) has been growing recently. To obtain higher throughput, systems employ multiple NAND Flash memories operating simultaneously in parallel. The available power for a mobile device is severely restricted and the peak total operating current may be high enough to cause large supply-voltage drop or even an unexpected system shutdown. Therefore it is important for NAND Flash memories to reduce operating power and peak operating current.
