Sentence examples for pcm- from inspiring English sources

He and Dr Eleftheriou have been applying the multi-level idea to PCM memory.This involves careful control of the length of the energy pulse that creates an amorphous region in the memory cell.

The IBM researchers have built PCM memory chips with 16 states (or four bits) per cell, and David Wright, a data-storage researcher at the University of Exeter, in England, has built individual PCM memory cells with 512 states (or nine bits) per cell.

Last year a group led by Eric Pop at the University of Illinois, Urbana-Champaign, demonstrated how a prototype PCM memory cell could be made that was just 10 nanometres across, bridging a gap between two carbon-nanotube electrodes.

PCM memory chips rely on glass-like materials called chalcogenides, typically made of a mixture of germanium, antimony and tellurium.Technology Quarterly Sweeping below deck A good kind of gas-guzzling Encouraging hydrophobia You, robot?

(For this reason PCM memory is sometimes called "resistive memory", and its individual cells are sometimes referred to as "memristors").You may already be relying on chalcogenides to store data without realising it, because they are used in re-writeable optical storage, such as CD-RW and DVD-RW discs.

Rent is slightly lower in Cardiff compared with the UK average; £804 PCM compared with the UK average of £811.

Drift causes the resistance of a cell to change, but not the thickness of the amorphous region, so this provides a more robust way to measure the cell's state.IBM is now working with SK Hynix to bring multi-level PCM-based memory chips to market.

Micron started selling its first PCM-based memory chips for mobile phones in July, offering 512-megabit and one-gigabit storage capacity.Thanks for the memoriesPCM memory chips have several advantages over flash memory, which works by trapping electrons in an enclosure called a "floating gate", built on top of a modified form of transistor.

But it promises to be smaller and faster than flash, and will probably be storing your photos, music and messages within a few years.The technology relies, as its name suggests, on special substances called phase-change materials (PCMs).

But for memory devices it is not their thermal properties that make PCMs so attractive.

Mecom's share price had risen 5.1% to 4.73p at 2.45pm today following confirmation of the PCM Uitgevers deal.
