    I know a little bit about Main Memory you have DRAM Chips and SDRAM Chips.

    DRAM Chips need to be Re Charged every Few ms to Hold the Bits in the Capacitor?
    Do I have this Right?

    SDRAM Chips do not need to be Re Charged every Few ms as long as the Power Supply is On?
    Do I have this Right?
    And I thought DRAM and SDRAM both need to be Re Charged?

    SRAM does not use Capacitors but Transistor MOSFETs.
    But Transistors just Turn On and Off they do not Hold a Charge.
    So how can it Hold Bits that the CPU may need?
