- - - - UDIMM <module>
        
        PC/DT
      - SODIMM <module>
        
        Notebook/Laptop
      - RDIMM <module>
        
        SERVER
      - Generations
        (the generations of DDR are not backwards compatible,
        but this also affects their compatibility with CPUs)
      - GDDR (Graphics Double Data Rate)
        DRAM for GPUs
        
        Generation
        
        GDDR6
        
        GDDR5
        
        GDDR & DDR are not cross-compatible
        Because they're form-factor depends on their application
        form-factor (physical configuration) is dependent on application
        
        Applications
        
        who require from us
    - - LPDDR <chip>
        
        Three Generations
        
        LPDDR3
        
        LPDDR4
        
        LPDDR4X
        
        need to get the actual part number
    - - Features
        
        low power consumption, low voltage requirements,
        and a smaller BGA packaging footprint
      - Applications
        
        Telecommunications
        
        Consumer Electronics
        
        Embedded Computing
      - Samsung Mobile DRAM
        zoomed-in view, front and back
  - - - Samsung, SK Hynix, and Micron
    - - Samsung, SK Hynix, and Micron
      - Kingston, ADATA, Ramaxel, and Transcend
    - - Samsung - 45.2%
        mostly used in consumer electronics: PCs and cell phones
      - SK Hynix - 27.6%
        mostly used in consumer electronics: PCs and cell phones
      - Micron - 23.1%
        Smith gets Micron memory cuz it's mainly used in industrial applications
      - Nanya - 2.1%
      - Others - 2.0%
  - - - How Nanya BGA look
      - How Samsung BGA look
    - - for the older generation applications
      - on DDR1, the short DIMM for laptops is shorter than for desktop
- - - - features
