The new 36 Gbps GDDR7 standard offers 50% improved speeds over the current 24 Gbps GDDR6X one from Micron. Peak GDDR7 bandwidth could reach 1.7 TB/s with a 384-bit bus. Samsung also plans to release 32 Gb DDR5 chips this year, and envisions a future where 1000-layer V-NAND storage could be possible by 2030.
[...] Furthermore, the 8.5 Gbps LPDDR5X DRAM solutions for mobile phones and ultrabooks are also expected to see increased adoption throughout the coming year.
The latest graphics cards from Nvidia, AMD, and Intel use GDDR6 or GDDR6X memory.
24 Gb DDR5 chips have already been announced as a stopgap between 16 Gb and 32 Gb, enabling memory modules with unusual capacities, e.g. 48 GiB instead of 32 or 64.
The 3D NAND currently in use by the industry has around 176 to 232 layers, so reaching 1000 layers could lead to quintupled SSD capacities.

SK Hynix to Manufacture 48 GiB and 96 GiB DDR5 Modules
Today SK Hynix is announcing the sampling of its next generation DDR5 memory. The headline is the commercialization of a new 24 gigabit die, offering 50% more capacity than the leading 16 gigabit dies currently used on high-capacity DDR5. Along with reportedly reducing power consumption by 25% by using SK Hynix's latest 1a nm process node and EUV technology, what fascinates me most is that we're going to get, for the first time in the PC space (to my knowledge), memory modules that are no longer powers of two.
For PC-based DDR memory, all the way back from DDR1 and prior, memory modules have been configured as a power of two in terms of storage. Whether that's 16 MiB to 256 MiB to 2 GiB to 32 GiB, I'm fairly certain that all of the memory modules that I've ever handled have been powers of two. The new announcement from SK Hynix showcases that the new 24 gigabit dies will allow the company to build DDR5 modules in capacities of 48 GiB and 96 GiB.
To be clear, the DDR5 official specification actually allows for capacities that are not direct powers of two. If we look to other types of memory, powers of two have been thrown out the window for a while, such as in smartphones. However PCs and Servers, as least the traditional ones, have followed the power of two mantra. One of the changes in memory design that is now driving regular modules to non-power of two capacities is that it is getting harder and harder to scale DRAM capacities. The time it takes to figure out the complexity of the technology to get a 2x improvement every time is too long, and memory vendors will start taking those intermediate steps to get product to market.
These are for server RDIMMs, at least for now.

So we have NAND memory compromising of several hundred layers and I don't know what the limit for this will be in the future. Will it depend solely on the memory's ability to dissipate heat, timing limitations because of the physical size of the layers or something else entirely?

Probably some advanced string stacking to get to 1000.

It is official; Netcraft now confirms: SN is dying
One more crippling bombshell hit the already beleaguered SN community when IDC confirmed that SN posting has dropped yet again, now down to less than a fraction of 1 percent of Slashdot. Coming close on the heels of a recent Netcraft survey which plainly states that SN has lost more users, this news serves to reinforce what we've known all along. SN is collapsing in complete disarray, as fittingly exemplified by failing dead last in a recent survey of news aggregators.
You don't need to be a Kreskin to predict SN's future. The hand writing is on the wall: SN faces a bleak future. In fact there won't be any future at all for SN because SN is dying. Things are looking very bad for SN. As many of us are already aware, SN continues to lose users and subscribers. Red ink flows like a river of blood.
SN is the most endangered of them all, having lost 93% of its users. The sudden and unpleasant departures of long time SN admins c0lo and The Mighty Buzzard only serve to underscore the point more clearly. There can no longer be any doubt: SN is dying.
Let's keep to the facts and look at the numbers.
Slashdot leader whipslash states that there are 7000 users of Slashdot. How many users of Pipedot are there? Let's see. The number of Slashdot versus Pipedot posts on Usenet is roughly in ratio of 5 to 1. Therefore there are about 7000/5 = 1400 Pipedot users. SN posts on Usenet are about one hundredth of the volume of Pipedot posts. Therefore there are about 14 users of SN. A recent article put Hacker News at about 80 percent of the news aggregator market. Therefore there are (7000+1400)*4 = 33600 Hacker News users. This is consistent with the number of Hacker News Usenet posts.
Due to the troubles of NCommander, abysmal management and so on, SN was taken over by martyb who is another troubled admin. Now martyb is also gone, and SN's corpse was turned over to Janrinok the Censor.
All major surveys show that SN has steadily declined in users and comments. SN is very sick and its long term survival prospects are very dim. If SN is to survive at all it will be among gun nuts like Runaway and khallow. SN continues to decay. Nothing short of a cockeyed miracle could save SN from its fate at this point in time. For all practical purposes, SN is dead.
Fact: SN is dying
