One Memory Bit SRAM - Georgia Tech - HPCA: Part 4

[@gofnek18484]

Let me thank you for the freaking clearest explanation of how SRAM working . Thanks a lot sir.

[@PavelVlasak]

Your videos has best explanations on dram, sram and memory chip organization i found so far. Thanks!

[@amandhakal8939]

Thank you man.... Your explanation solved my doubts which had lasted for 2 years... Thumbs up.... :)

[@reneeovos]

Thanks for clear explanation!

[@bhanuchaudhary9958]

Very crisp explanation dude .... :)

[@RockzUmang]

What an explanation 🤘🏻

[@harryjackling9118]

Awesome explanation dude

[@samc5678]

What do we do when we want to change the bit to 0? will having a bitline to 0 defeat the current value in inverters?

[@mehmedguler4252]

excellent explanation!

[@charlessamuellasiste2752]

The stored bit loops continuously between the two inverters. Is this the reason why data is lost if power to the SRAM is cut?

[@AlbertRei3424]

yes

[@jpohbw]

Very nice!

[@exquisitedog8069]

you rock pal !

[@zjinia]

nice explanation.thanks a lot!!

Does the loop of inverters waste energy? is there a way to reduce the power consumption from them?

[@shashankrao4443]

Loop of inverter has energy consumption. You can reduce the power consumption by designing low power CMOS. More info to start with: bwrcs.eecs.berkeley.edu/Classes/IcBook/SLIDES/slides4a.pdf

[@shadowmaster1356]

Well, static power dissipation is zero( i.e. when the transients are not present in the cell). Regarding dynamic power consumption, that will to a large extent depend on the bit line capacitances that the inverters will need to drive.

[@gofnek18484]

fXcking awesome explanation baby

[@brandm5176]

Super!

[@Anveshana837]

Not able to understand how to read data..

[@ARBITRON4000]

You just let the inverters drive the two bit lines in order to read.

[@beajanos9277]

genial,!!!!!

[@miguelfsousa]

what actually happens when he says that "the stronger 1 defeats the 0"?

[@ARBITRON4000]

If inverters are trying to drive a 0 and you want it to instead drive a 1 (because you want to store a 1), you want to "defeat" the inverter's value and force it to drive a 1. So the only way you can do that in this scenario is by having the 1 (the bit line) be much stronger than the 0 (the inverters), which will force the inverter to change to drive a 1 instead.
