SLC = 1 bit per cell; enterprise grade (100,000 cycles) and therefore very fast but very expensive for the amount of storage
MLC = 2 bits per cell; still very fast but offered in larger capacities and cheaper than SLC, though somewhat less reliable (10,000 cycles); early consumer SSDs were MLC and even most power users would be hard pressed to wear out one of these drives without exposing it to dirty voltage and/or constant read/writes such as 24/7 surveillance recording
TLC = 3 bits per cell; dominant consumer drive; less reliable (3,000 cycles) and slower than SLC or MLC, but offers even larger capacities at a much more reasonable price point
QLC = 4 bits per cell; slowest and cheapest of consumer grade drives; reliability is significantly lower than other technologies (1,000 cycles), however, this is somewhat offset with the use of 3D architecture and the larger capacities as you won't really start "wearing" the drive until you fill it over 50%
3D NAND - bits can be stored on a cell both horizontally and vertically which decreases their sensitivity to voltage differences and decreases errors, while also allowing for higher capacities and lower power consumption.
For reference, a "cycle" is a "program/erase" cycle, which means data is written to a cell, the cell is erased, and then rewritten.
To answer the poster's question: DRAM is a separate chip built into the SSD which functions sort of like the RAM in your PC. It stores data temporarily to increase access speeds to it, but then that data is lost when the power is turned off.
MLC/TLC/QLC drives with "SLC Cache" mean that there is a portion of the drive's storage that is ear-marked to function like SLC up to a point; frequently accessed data is written to this space to increase access speeds, but as the drive becomes full, this space stops functioning as a cache and reverts to normal MLC/TLC/QLC storage. The benefit to this method is that the data remains in storage on these cells even after power is removed. The downside is that this cache disappears as the drive becomes full, which isn't a problem for DRAM.

it has SLC which are super fast writes and the most reliable cell technology, equaling 4400ish MBs writes and 1200 TBW on 2TB. and its gen4
btw, who can tell a difference between 3000 and 6000 MB writes?
the only downside is no DRAM

It sounds like you didn't read or didn't understand what you read, but definitely didn't do any homework. I did not tell a lie!

These Team Group drives for spares and low end barebones pc.
