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 …

Flash storage: Has the hype become reality?

Comment Is the flash storage business a hype-filled wonderland or is flash-based technology making real inroads into IT? Flash arrays provide much faster access to data, because of SSD’s lower latency compared to disk drives but they are more expensive to buy. This can be justified by looking at potentially lower total cost of …
