Memory

Process control systems used for advanced packaging of dram products in Korea and China facilities; additional orders expected to meet capacity ramp. Rudolph Technologies announced that it has received orders for over $15 million of legacy and new process control systems from a memory manufacturer based in Asia. The systems will be used by a top-tier memory chip maker as they rapidly transition high-end DRAM (DDR4, DDR5) and HBM DRAM packaging from wire bonding to advanced packaging architectures.

Implementing Memcache with NAND or 3D XPoint produces near-DRAM cache performance at a much lower cost, IBM claims. Memcache is an open source distributed memory system launched in 2003. These databases are much larger and DRAM has remained expensive – indeed prices increased 47 per cent, according to IBM more than 700 applications use Memcache and many public clouds offer a managed Memcache service. For instance, LinkedIn, Airbnb and Twitter use Memcache to avoid accessing databases on storage and so reduce speed query response times.

Intel's Optane products so far fall into one of two categories. At the high end is the flagship P4800X enterprise SSD and its derivatives for the enthusiast market. At the low end are the small M.2 modules intended primarily for caching use. It's this latter category that is being upgraded from PCIe 3x2 to a PCIe 3x4 host interface, moving the cache drives and small Optane SSDs more toward the mainstream NVMe SSD market.

An article written by Mark LaPedus for Semiconductor Engineering - Progress on 3D-ICs, using HBM with fan-outs, and other new approaches. A new wave of 2.5D/3D, fan-out and other advanced IC packages is expected to flood the market over the next year.

Emerging non-volatile memory (NVM) was long restricted to niche applications because of poor scalability, high cost, and a lack of support from major memory makers. But in 2015, after more than 15 years in development, the first PCM-based technology for storage-class memory applications was presented by Micron and Intel: its name, 3D XPoint. However, it took these companies another two years before introducing their first commercial products. Two years after, Intel introduced Optane SSDs and storage accelerators. Developments should not stop there as persistent memory modules, the Optane DIMMs are expected in 2019.

An article written by Scott Thornton for Microcontrollertips - A data-centric economy is evolving. The Samsung Galaxy Note 9 debuted with 8 GB RAM and one terabyte (TB) of storage (purchasing a 512 GB SD card bumps it to 1 TB). The price tag is well over $1,000, so the rest of us will have to buy 1 TB of cloud storage from Google for $10/month to unload the 700 feature films or 500,000 photos that we collect in everyday life. (Note that 1 TB is 1,000 GB and that these are estimates).
