SRAM vs DRAM : How SRAM Works? How DRAM Works? Why SRAM is faster than DRAM?

[@ulysses_grant]

This is the best lecture on DRAMs and SRAMs I've ever seen.

[@RakeshGupta-ft6cc]

Instead of just explaining concepts like any other channel,you tried to look into common doubts and explained them.That's nice

[@TechnicalGamerDino99]

Cant agree more

[@cosmoszeeistflight]

thanks a lot bro... again thks for English... many Indian education channels r in Hindi... I think it's every usefull for non-hindi learners

[@habenetsay9448]

THANKS WHE ARE DEPRESSED NON HINDI LEARNS CONTINUOE LIKE THAT

Very well explained in a simple way.

[@kaptansingh4700]

I could not get the line 8:37. Can you please rephrase that. Thanks for this amazing explanation. Keep up the good work.

[@ALLABOUTELECTRONICS]

What I meant to say was, using (4T) cell, we can reduce number of transistors (instead of bit) that is required for storing 1 bit of information. I hope, it will clear your doubt.

[@pankajkupra1251]

very easy to understand because you have used simple language and and a perfect reason behind why we use this memory. thank you so much. I believe you will further make many videos related to topic also like electronics devices and embedded systems also.

[@prashantdudam3931]

Nice video and its very easy to understand due to simple language have used. Thanks

Excellent lecture!!!!! Thanks

[@SeekersudiP]

great info bro, your accent is perfect.

[@world-traveler880]

Great video! Very good and clear explanation! Thanks man!

[@FreeCircuitLab]

During write operation, when we apply 1 to the output of a previously zeroed inverter, in the instant before its transition it will short the input voltage to ground, so for some pico second, the current will be very high upto a few Amps!! So, it will load the power line and will shut off the whole operation for a picosecond!!! Please explain it to me.

[@aviandragon1390]

A. Research the meaning of the word pedantic. B. The traces on the PCB will have resistance, inductance, and capacitance which prevent an instantaneous transition to infinite current. C. The source voltage has a limit of current it can source. D. This is a super simplified diagram of the circuit. Obviously there are going to be current limiting resistors in any circuit. Don't act dumb.

[@newspresentersacdemybd8786]

But Sir, why we need two inverters in case of SRAM? I think one inverter will be enough...then why two?

[@anithakumar7864]

excellent and simple explanation sir.pls share 8085 microprocessor course by you sir

[@kundankumar-ll8in]

you are amazing..sir

[@mohddanish5644]

very nicely explained...keep it up

[@shubhamnayak9369]

Around 8:40 you said that by using 4 transistor we can reduce no. Of bits required to store the bits..I didn't understand this part. Can u explain?

[@ArneChristianRosenfeldt]

Is probably none sense. And while I have to admit that there are many resistors on a lot of PCBs, there are none inside an IC.

[@SumriseHD]

Suggestion: Don't pause and raise your voice after every 3rd word. Example: The data [...] will be available at the? Data. (4:17) This is very disruptive. Other than that, well made graphics. PS: Maybe try to be pricise and don't say so many things multiple times

[@unglaubichuberlieber8048]

thanks a very good tutorial for beginners ...

[@reemabharti2276]

Nice video...quite helpful

[@ChristmasEve777]

I still don't understand how that flip-flop loop in SRAM maintains the voltage without needing a refresh. I know there is no capacitor so you don't have to worry about a capacitor discharging. However, if you're not performing any operations on that memory cell for a long time, how does that voltage not fade?

[@ChristmasEve777]

OOPS, never mind. I just looked at the diagram again where you show all 6 transistors instead of showing each pair as a not gate. I can see that it's connected to VDD. So EVERY bit has a constant connection to power. That would also explain how an SRAM cell can turn a 0 into a 1. I'll leave both of these comments here in case someone else thinks the way I just did after seeing the video.

[@darshanasamanpura9325]

Beautifully explained !!!

[@tsYeng]

Thank you for the teaching, very useful to me (dummy)

[@VitaminVS]

Nice explaination but how can a transistor pair store a voltage?

[@anuragchauhan6312]

Hi Vikash, Here transistors are used to get a latch of invertors(Latch/FF are used as storage element). And If you see at 7:35 you can see BL (Bit Lines) are controlling only Gates for these CMOS-Invertors and also connected to Output in READ mode. And voltage sources VDD and GND are present. Let say output of first and second invertors are INV-12, INV-34. So INV-12 is controlling gate of Second invertor. INV-34 is controlling gate of First invertor. Now consider that you want to WRITE '1' in this CELL. So BL == 1, and BL(BAR) == 0. It means INV-12 == 1: transistor 3 == open circuit transistor 4 == close circuit Output of second invertor is '0' that is matching with supported voltage of BL(BAR) INV-34 == 0: transistor 1 == close circuit transistor 2 == open circuit Output of first invertor is '1' that is matching with supported voltage of BL And all these operation takes place only when WL make close circuits for 5 and 6 . So in absence of WL there is no change in gate conditions so no change in invertor conditions too. And output voltage controlled by VDD and GND and depending on current conditions of 1,2,3,4, transistors. In READ mode: we don't apply EXTREAM voltage on BLs, we just apply adequate voltage to check direction of resultant(of BL and Output voltage of invertor) voltage flow to decide Logic '0' or '1'.

Can I use dram +sdram dual channel?

[@emilioortega9487]

I got everything but I don't actually get what you mean by "density" when you talk about the rams

[@oliverenede7839]

Emilio Ortega by density he means the amount of data it can hold for example a typical ram sticks nowadays can hold 8GB of data where’s the cache memory in typical CPU’s is very low like around 6MB of data

[@emilioortega9487]

@@oliverenede7839 Hi thanks for answering, now it makes sense because he in the video talked about the number of memory cells and said Sram had less than DRAM :s and that's what I don't understand

[@vijayramachandran2943]

How they refreshing the capacitor periodically. And also my doubt is during the refreshing cycle the capacitor can become logic 1 suppose the data was logic 0. Please explain

[@shehanbartholomeusz7511]

1.34 "Primary storage element like hard disk drive" isnt it secondary?

[@MrDombosfi]

Is the SRAM with 4Cells the PSRAM (pseudo static RAM)?

[@indrajitdas9553]

basically SRAM cell is a bi stable multivibrator

[@nayanbhatia3531]

Sir how is value being read from the SRAM if there are no capacitors to store the charge or no storing device to hold the voltage

[@anuragchauhan6312]

If you know about Flip Flop Or Latch then you can understand with the help of Transistors (1/2/3/4) we are trying to make a memory cell that can maintain a state as we do in FF/Latch. And voltage level we are getting as per the state of these transistor either High(say 5V) or Low (say 0V). These voltage levels depends on the source voltages (VDD/GND). HTH

[@chinmayrozekar9624]

12:13 I did not understand the SRAM WRITE operation.

[@belikelambo9137]

I can't understand what u are saying at 6:00 . Can u please elaborate it how we are increasing the reading speed further?= 2nd method

[@ALLABOUTELECTRONICS]

What I mean to say is instead of measuring the absolute value of the voltage, just by measuring the incremental voltage (increase or decrease in the voltage at the bit line) the reading speed can be increased further, as now no need to wait till the voltage at the bit line reaches the final value. I hope it will clear your doubt.

[@lichenguang8073]

Thanks for the clear explanation, also thanks for the subtitle23333

[@RahulKumar-oz2mc]

at 8:39 , you said 'we can reduce no. of bits' how bits?

[@ALLABOUTELECTRONICS]

What I meant was, we can reduce number of transistors. (4 transistors in comparison to 6 transistor)

[@TechnicalGamerDino99]

Thank u

[@ManojkrishnaJagarlamudi]

How periodic refresh cycles done in Dram for the cap

[@nightwitchsara]

I was wondering this! maybe there's a mosfet connected to the capacitor with an AC signal at the gate? if you used the clock cycle of the computer with a phase, I bet you could get it to charge only when there are no reads or writes occurring. really not sure though!

[@vandanivasanth2682]

Thank you bro

[@annemarydavid8620]

[@enginstud8852]

Hi, in an array of SRAM cell, can a specific celle be selected and written to ? It seems that the Word Line enable an entire Row of cell so we have to write and read to the entire row, is it correct ?

[@ArneChristianRosenfeldt]

I think you read out a complete row. You write to one cell by applying high enough voltage over its bit lines.
