Whither BORAM?

There used to be a fair amount of Block Oriented Random Access Memory (BORAM) literature, but I can't find anything in wiki on them. Basically, a BORAM is a RAM with a huge word size; typically, a page. At first glance it would appear that contemporary removable storage devices are using this technology. So is this just a change in nomenclature, or have they gone away? Should they be mentioned in this article? -- Shmuel (Seymour J.) Metz Username:Chatul (talk) 16:33, 10 July 2025 (UTC)[reply]

no they haven't gone away, I remember a lot of talk about doing sequential access, and I think vaguely that the sequential access in DDR JEDEC standard allows block-based lookups to be initiated "ahead of when the result is needed". doing a bit of guess-work / reverse-engineering I think what is happening is that DRAM chips do RAID-like "striping" (RAID0?( so the speed of "blocks" which never went above 100 mhz can APPEAR to be much faster... but only if they are accessed sequentially. answering a bit more directly: the clue should be that JEDEC is a closed and secretive standards organisation....

found the term - Interleaved_memory a sort-of RAID striping. Lkcl (talk) 04:46, 6 August 2025 (UTC)[reply]

note that the interleaving described there is going on inside the DRAM IC, to the extent that wires in both the SDRAM and DRAM ICs are actually named "Bank". but i expect a much finer grain of interleaving, i mean you have to. you simply cannot get 100mhz blocks to do 800mhz 1033mhz 2666mhz etc etc no matter how much you wish it to be possible.

OpenRAM and other efforts

i saw a few years ago that projects such as OpenRAM had managed to get the underlying block speed of RAM up to 150 mhz. the proprietary DRAM industry has been keeping the core block rate artificially at 100 mhz for decades. Lkcl (talk) 00:29, 6 August 2025 (UTC)[reply]

Should we update this sentence about RAM v HDDs ?

This section could be made more relevant by including how it compares with SSDs, which are now as or more common that HDDs.

Excessive use of this mechanism results in thrashing and generally hampers overall system performance, mainly because hard drives are far slower than RAM.

One source that could be useful is the speed declared in the Memory Hierarchy table https://en.wikipedia.org/wiki/Memory_hierarchy

It can be a simple update because hard drives and SSDs are far slower than RAM. And sure, use that cite (0.2 ms). ~Kvng (talk) 23:32, 25 November 2025 (UTC)[reply]

Recent RAM shortage

As of now, due to some companies heavily investing in RAM for their data centers and other related projects, there is a shortage of RAM, with RAM prices going up on the market due to the law of supply and demand, even during Black Friday. I feel like this is worthy of note in the article, or at least in a related article. Maddox121 ForgotHisPassword (talk) 00:05, 29 November 2025 (UTC)[reply]

I've created a draft, which is Draft:2025 RAM shortage.FSlolhehe (talk) 06:01, 3 December 2025 (UTC)[reply]
