Time stamps for the different topics covered in the video. 0:52 SRAM vs DRAM 2:54 Dynamic RAM (DRAM) 3:56 Read and Write Operations on DRAM 7:15 Static RAM (SRAM) 9:22 Read and Write Operations on SRAM
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.
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.
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.
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.
since intel/amd days are numbering...in your future time, you might add the relation ship between arm and dram or sram or both...regardless have a great day and DO ENJOY LIFE !!!
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
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?
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.
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'.
There are different playlist on the channel . You can refer them. For example, for MOSFET there is a separate playlist. You can refer that for more info.
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
@@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

Kash tum hindi mein explain karte then it will be more clear
"SRAM (Cache) is going to die out in the future." Ha ha amd 9800x3d go brbrbrbrbr.
This is the best lecture on DRAMs and SRAMs I've ever seen.
Instead of just explaining concepts like any other channel,you tried to look into common doubts and explained them.That's nice
Cant agree more
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
THANKS WHE ARE DEPRESSED NON HINDI LEARNS CONTINUOE LIKE THAT
wow my English skill is very poor but I can understand this lecture cause you uploaded subtitles...! thx for great lecture and kind subtitle !
Better than my teacher ever could teach
Easier to understand than my textbook, thank you sir!

Why is it that asian dudes have the best content about computers and stuff? Not trying to offend! It's just a little trend that i've noticed
I could not get the line 8:37. Can you please rephrase that.
Thanks for this amazing explanation. Keep up the good work.

Good video
Thank you man
Fantastic thanks
super excited sir
I love this video thank you!!!
basically SRAM cell is a bi stable multivibrator
Very good video but little fast...
Thanks for the clear explanation, also thanks for the subtitle23333
But Sir, why we need two inverters in case of SRAM? I think one inverter will be enough...then why two?
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?

Where can i learn circuit components like you mensloned in this video?
There are different playlist on the channel . You can refer them. For example, for MOSFET there is a separate playlist. You can refer that for more info.
@@ALLABOUTELECTRONICS Thank you so much
Cпасибо, у меня как раз скоро зачёт по этой теме =)
удачи
Amazing!
I got everything but I don't actually get what you mean by "density" when you talk about the rams
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

Thank you a lot！ Sir
Tanqq sir
Super bro ...pls explain impedance
I have already made a video on that.
Here is the link : th-cam.com/video/7jw2_x8dyQ8/w-d-xo.html
Very clear
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?
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.
Thank u
Thanks mate
Cache memory ke andar kon sa semiconductor technicq use hota hai......mos ya transistor...??
Please batao
thank you
Thank you sir
I'd like to learn how to add something to calculate memory probability
The theme song for this channel always makes me feel depressed
And ssd kon sa technology use karta hai dram ya sram ??
Batao please
Can you use SRAM and DRAM inside one PC in the same time?
kya ye video Japanese me available hai....?
DRAM 2nd point i.e It is fast compared to the primary storage memory like HDDs but it slower compared to the SRAM. Is HDD primary storage device?
Perfect!!
12:13 I did not understand the SRAM WRITE operation.
Sir shall you make a video on intergreted and non intergreted motherboard plz sir
thanks
