What is 3D XPoint technology?

What is 3D XPoint technology?

3D XPoint (pronounced three-D cross point) is a non-volatile memory (NVM) technology developed jointly by Intel and Micron Technology. As the memory is inherently fast, and byte-addressable, techniques such as read-modify-write and caching used to enhance traditional SSDs are not needed to obtain high performance.

Is 3D XPoint phase change memory?

3D XPoint Memory last December. The 2nd gen. XPoint Memory has four-layer Phase Change Memory (PCM) structure for 256Gb die. The Optane P5800X is said to be the fastest enterprise SSD with PCIe NVMe 4.0 x4 on the market.

Who invented 3D XPoint memory?

Micron Technology
Like many system architects the world over, we had high hopes for the 3D XPoint variant of phase change memory (PCM) when it launched with much fanfare back in July 2015 after being developed jointly by Intel and Micron Technology for many, many years.

What happened 3D XPoint?

Micron announced on March 16 that it would immediately cease development of 3D XPoint and shift resources to new types of memory-centric products that use the emerging Compute Express Link (CXL) standard to connect compute, storage and any type of memory.

Is 3D XPoint NAND?

Intel and Micron co-developed 3D XPoint memory, revealed in 2015 as a non-volatile memory technology with higher performance and endurance than NAND flash memory.

Is Optane better than SSD?

Tests have shown that Intel Optane is better for applications with read-intensive access patterns. Its advantage over other high-performance SSDs is less pronounced when it comes to write-intensive workloads. To make use of Optane’s speed and performance, Optane SSDs use the NVMe interface which is superior to SATA.

Is 3D XPoint dead?

Computer memory and data storage manufacturer Micron has decided to cease the production of the 3D XPoint memory, reportedly owing to poor sales. Micron developed the 3D XPoint jointly with Intel in 2015, with the non-volatile memory claiming to offer higher performance and endurance than the popular NAND flash rival.

What is the difference between V NAND and 3D NAND?

That something was the invention of 3D V-NAND. The major difference between 3D V-NAND and the traditional planar NAND that came before is a matter of stacking. Samsung’s proprietary V-NAND technology, as used in the 850 PRO, involves stacking 32 cell layers of cells on top of one another.

What is 2D NAND and 3D NAND?

3D NAND offers a higher capacity potential than 2D NAND in a smaller physical space. 3D NAND can reduce the cost per gigabyte in comparison with planar NAND, improve electric use in order to decrease power consumption, increase reliability, and increase data writing performance.

How does 3D XPoint work?

To improve storage density, the 3D XPoint cells can be stacked in three dimensions. This activates the selector and enables voltage through to the cell to initiate the bulk property change. For read operations, a different voltage is sent through to determine whether the cell is in a high- or low-resistance state.

How do I use Optane memory?

To enable Intel Optane memory using the Intel Rapid Storage Technology application, use the following instructions:

1. Open the Intel Rapid Storage Technology application.
2. Click the Intel Optane memory tab.
3. Click Enable.
4. Select a compatible fast drive, and then click Yes.

Is Optane an NVMe?

The Intel Optane drive is also based on the NVMe interface and PCIe bus but uses the new 3D XPoint flash memory developed by Intel for ultimate performance. Optane SSD offers extreme performance and fast latency but they are expensive. Most Optane drive currently need to be mounted on a PCI slot.

Who is the creator of 3D XPoint memory?

3D XPoint is memory storage technology jointly developed by Intel and Micron Technology Inc. The two vendors have described this new technology as filling a gap in the storage market between dynamic RAM (DRAM) and NAND flash. Download this free guide.

What makes 3D XPoint different from other flash memory?

3D XPoint has a different architecture from other flash products. It’s reputed to be based on phase-change memory technology, with a transistor-less, cross-point architecture that positions selectors and memory cells at the intersection of perpendicular wires.

How does 3D XPoint work in a data center?

The combo allows 3D XPoint to fill a gap in the data center storage hierarchy that includes SRAM on the processor, DRAM, NAND flash (SSDs), hard disk drives and magnetic tape or optical discs. It would fit between volatile DRAM and non-volatile NAND flash solid state storage.

What are the IOPS of 3D XPoint memory?

Intel’s first 3D XPoint SSD – the P4800X — can perform up to 550,000 read input/output operations per second (IOPS) and 500,000 write IOPS at queue depths of 16 or fewer. While Intel’s top-tier NAND-flash based SSDs can achieve 400,000 IOPS or better, they only do so with deeper queue depths.
