SRAM vs DRAM
The cluster focuses on comparisons between SRAM (used in CPU caches) and DRAM (main system memory), discussing differences in speed, latency, power, density, and refresh requirements, often in the context of new on-package or integrated memory in chips.

Don’t most processors use on-chip SRAM for their cache, which is faster than DRAM?
Faster than DRAM from the 90's.
Would it be lower power than DRAM?
are speeds of bleeding edge mem devices getting close to RAM?
At least in older CPUs the caches were SRAM (static RAM). It is complicated but requires no refreshing. DRAM is basically just a capacitor per bit and capacitors leak so you constantly have to refresh the entire memory space. When the CPU sends a request to RAM, the memory controller might be too busy refreshing the soon to decay parts to actually respond right away. And if I recall correctly when you read from DRAM you destroy what was there so the process is to read it, then write it back, the
Would achievable SRAM cache size per mm2 work?
Yes, it said it was as fast as DRAM, not SRAM (the latter is what is used for cache and registers).
What is the latency like vs DRAM?
We’re talking DRAM here, not NAND?
You're confusing DRAM and CPUs - CPUs almost only use static SRAM cells internally which don't require refresh
