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.

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'.

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.

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

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

Won't the precharged bit line write into the capacitor during the read operation of the capacitor containing no charge?
@amoghk.m.6769
@amoghk.m.6769 6 жыл бұрын
Sharon Alexander Not really. "Precharged" means that the data line WAS being continuously driven to be at 1V but now, it IS not. And it has remained at 1V simply because it hasn't been given any reason to change(it's like 1V was being supplied and suddenly, the voltage source was disconnected). The line is now free to take any voltage that tries to drive it. So, during the read operation, the capacitor will drive the line. However, during the write operation, the data line isn't "precharged" but is continuously driven from some source. Then, the capacitor will be one being driven.
