PCM IBM chip, photo IBM

Great, IBM has had a PCM breakthrough. Who exactly is going to manufacture?

Analysis IBM has demonstrated a 3-bit Phase-Change Memory chip with IBM Zurich researcher Dr. Haris Pozidis talking about it in a YouTube video and not mentioning 3D XPoint once. The idea is to counter the relatively high cost of PCM chips by giving them 3 bits per cell, TLC or triple-level cells, instead of just one - clever. This …

Memory and storage boundary changes

Analysis Latency is always the storage access bête noire. No one likes to wait, least of all VMs hungry for data access in multi-threaded, multi-core, multi-socket, virtualized servers. Processors aren't getting that much faster as Moore's Law runs out of steam, so attention is turning to fixing IO delays as a way of getting our …

HPE is going to unleash a Machine on us. Here's how it might play out

Comment At the far end of HPE's storage and compute strategy is the Machine, the dynamically composable infrastructure thing with separately scalable compute, memory/storage and networking resources. It has a huge flat and persistent memory space using storage-class memory (SCM). It was supposed to use memristors, but since that …

Hey, Intel and Micron: XPoint is phase-change memory, right? Or is it? Yes. No. Yes

Comment So, is XPoint memory phase-change memory ... or not? An IM Flash Technologies co-CEO just gave a strong signal it might be phase-change, but doubt remains as Intel and Micron have kept their secret process ingredient hidden. IMFT is the Intel/Micron joint venture to manufacture flash chips in Lehi, Utah. Guy Blalock and Keyvan …

SanDisk, HP take on Micron and Intel’s faster-than-flash XPoint

+Comment HP and SanDisk are joining forces to combat the Intel/Micron 3D XPoint memory threat, and developing their own Storage-Class Memory (SCM) technology. SCM is persistent memory that runs at DRAM or near-DRAM speed but is less costly, enabling in-memory computing without any overhead of writing to slower persistent data storage …

XPoint memory ruminations: Expert says it's not PCM

Comment A presentation at the Flash Memory Summit contained speculation about Intel/Micron’s 3D XPoint memory – what it is and how Intel might use it. We’ve tested some of its contents with a knowledgeable industry expert and can cast a little more light, hopefully, on what it is and where it’s going. The Thursday August 13 …

A day may come when flash memory is USELESS. But today is not that day

The era of flash memory is anticipated to run out of road in the 2020s and newer technologies involving resistance and electron spin are poised to take over, delivering higher capacities, greater speed and DRAM-style addressability. Some people ask if one of these new technologies could actually unify dynamic memory (RAM) and …
