Embedding Memory in Next Generation Handset Designs

Single-bit-per-cell NOR is more expensive per megabit than NAND, but its price per device is typically lower than NAND at the densities that are appropriate for most on-board requirements. In general, the price per bit of NOR is also less than SRAM and PSRAM, though it may be somewhat higher than that of LP SDRAM. New MLC NOR solutions enable two data bits to be stored per cell, and substantially reduce the total cost per megabit of NOR memory.
