    Serial NOR Flash gains Popularity in Feature Mobile Phones - Mobile Handset Market & Popular Flash Solutions. 2.xG is Alive & Well Focus on “Smart-phone-like” & “Ultra-Low-Cost"" How NOR Flash (code storage) is used? SnD (Store & Download) or XIP (Execution in Place) SnD: Shadowing the code from Flash Memory to DRAM. XIP: Direct Access & Execution from Flash Memory. Why does 8-pin Serial NOR become popular? Lower overall cost ! (Flash+ASIC_support+PCB_savings), Quad-IO improves Serial performance in par with previous Parallel Flash, Wide range densities (1Mb-256Mb+) with identical footprint in industry standard packages (SOIC / SON), Simplifies PCB layout, Reduces system noise & EMI (esp. pSRAM/mDDR SiP with Baseband), Lower power consumption than Parallel Flash, Well supported by all key NOR vendors with continuous scaling. ayout with Discrete Serial Flash, Layout with Parallel Flash MCP. SnD using Quad-IO Serial Flash. Quad-IO Serial Flash throughput matches well with page mode parallel Flash for SnD (Large piece of data shadowing from Flash to RAM). XIP using Quad-IO Serial Flash - Quad-IO Serial Flash also matches page mode parallel Flash access speed for XiP (Small piece of data; e.g. 16 words for cache-line) Note: Parallel with 70ns; Parallel plus page mode with 90/30ns; MXIC 6-Dummy cycle Fast QPI with 104MHz. Serial Flash to meet Market Needs.
