# NewsMicron Preps 32GB DDR5 Chips, Opening Doors to 1TB Modules

They are showing a picture of a chart regarding the HBM3+ stuff, for ddr5 RAM sticks. Oopppps

Calculations: 1Gb = 125MB

So 32Gb would equal 4GB.

If Micron is just now coming up with 4GB memory sticks I think they might be a little behind the curve.

You don't seem to understand that it's referring to the individual memory chips on the memory sticks. At the client level 32GB of DDR5 has 16 individual chips because they're 16Gb, 48GB also has 16 chips because they're 24Gb so this would allow for 64GB with the same number of chips. In theory this would allow client devices to have 256GB maximum DRAM capacity.

Great they can pack more density into an IC chip is what this tells me. Opening the door to bigger capacity UDIMMs for DDR5.
There OC potential will be limited though compared to bigger die manufacturers (at present).

24Gb GDDR7 is the real story here, in my opinion. The excuse Nvidia and AMD roll out for why the 4060 and 7600 can't be more than 8GB is that they have 128-bit busses. With 24Gb modules, they'd be able to do 12GB on 128 bits. Or 16GB on 192 bits. Ideally, they get their heads out of their rears and increase the bus width of low-end and midrange parts, but the option to have 24Gb modules is quite nice as well.

Going forward the company plans 192GB and 256GB DDR5 modules.
@ 4 GiB DDR5 DRAM Packages
192 GiB = 1⅓H.3R.2S DIMMs
256 GiB = 1⅔H.4R.2S DIMMS

Perfect for Enterprise Server racks where 3 Row and 4 Row DIMMs would make sense.

A friend of mine has been eagerly waiting for 128GB DDR5 DIMM Modules.

So the fact that they're coming next year, his personal Rendering Station will be very happy.

I think you mean 32 Gb, not 32 GB.
Apart from anything else, you can also just look at the slide.

Calculations: 1Gb = 125MB
Fair point: they should've said Gib, which is equivalent to 128 MiB

When talking about networking speeds or disk capacity, we usually mean G (i.e. 10^9). When talking about RAM, we usually mean Gi (i.e. 2^30).

You don't seem to understand that it's referring to the individual memory chips on the memory sticks. At the client level 32GB of DDR5 has 16 individual chips because they're 16Gb, 48GB also has 16 chips because they're 24Gb so this would allow for 64GB with the same number of chips.

Yes, and the article also talks about 8-high stacking, which just confirms the 32 Gb figure is referring to a single 2D die.

"32Gb devices open doors to 1TB DDR5 modules (which use 32 8-Hi 32Gb stacks)"

32 Gib/die * 8 dies/stack * 32 stacks/module = 8192 Gib/module

8192 Gib/module / 8 bits per Byte = 1024 GiB/module

That's where the headline figure of 1 TiB/module comes from.

128 GB UDIMMs or RDIMMs?

With 32 Gib dies, the max UDIMM size will probably be just 64 GiB. That's because I think UDIMMs are limited to dual-rank, which I believe limits you to 16 chips. Stacking the dies probably pushes past the point where you need registers (i.e. RDIMMs).

These have been on their product matrix since May at the very least:
