What's the difference between 4T SRAM and 4 bit SRAM ?

I am new to SRAM

Can Someone please guide me ?

Difference between 4T SRAM and 4 bit SRAM

simple schematic design CMOS for 4 bit SRAM, 6 bit SRAM

Thank you

Your help is very much appreciated:grin:

4T SRAM is the simplest unit cell design. A 4 bit SRAM
would have (4) 4T (or 6T) bit cells (plus write and sense
overhead, etc.). 4T cell may or may not be more compact
than 6T, depending on how you get your pullup resistor
built. You would want a very high value, which is usually
much fatter than a minimum geometry PMOSFET. The
main virtue of 4T cells being that you can build them
without PMOS (for what little that's worth in the modern
era). A resistor built up in the interconnect stack
somewhere, could make a compact 4T design by a 2.5-D
sort of layup. But this is specialty-flow territory, in case
you were imagining integrating a RAM block in vanilla
CMOS.

Now I'm fairly confident that Mr. Go0glEz would serve
you up plenty of pictures from a '4T SRAM' and '6T SRAM'
keyword search.

thank you very much bro

Dear bro,

I have try my best to search from google.

i can search tonnes of 6T SRAM

but i don't get it how do i prove that is a 4 bit SRAM


What is this meaning ?
"depending on how you get your pullup resistor
built"


Can you show me a simplify complete 4 bit SRAM schematic ?



Your help and guidance i appreciated very much

Thank you
