Everything in electronics has capacitors, inductors & resistors. The trick is understanding how they work, instead of just trolling with ignorant questions. -- Anyone wanting to run for any political office in the US should have to have a DD214, and a honorable discharge.

Twin-Transistor RAM does not contain capacitors http://en.wikipedia.org/wiki/Twin_Transistor_RAM quote: "TTRAM is similar to conventional one-transistor, one-capacitor DRAM in concept, but eliminates the capacitor by relying on the floating body effect inherent in a silicon on insulator (SOI) manufacturing process." Another question arises. Does Twin-Transistor RAM have a longer duration of data remanence -- when power-offed -- than SN7489? |
