The reason for this alacrity of memory formation is the fact that for every person, every place -- and probably a lot of other concepts, too -- there are individual memory cells
that are specifically assigned to that memory.
The technology developed by BeSang allows vertical memory cells
to be stacked on top of conventional CMOS logic within a semiconductor chip, using seamless and unlimited interconnects between device layers.
DIFFERENT STROKES Although most champions of phase-change memory are betting on GST-based memory cells
, some researchers have taken another tack.
Small but quick memory cells
can be designed by using the results of the research for the production of computers, mobile phones and smart TVs.
Yeo, PhD, assistant professor in the Department of Cellular and Molecular Medicine and Institute for Genomic Medicine, said that researchers have been trying for a very long time to understand when and how T lymphocytes give rise to effector and memory cells
during an infection.
Forrest anticipates that an array of polymer memory cells
on a 1-millimeter-square chip could store 1 megabit of information.
In prototype phase-change memory cells
fabricated using this structure, programming operation has been verified with a current of 100 [eth]-A at a power supply voltage of 1.
The device is based on the principles of resistive memory, which can be used to create memory cells
that are smaller, operate at a higher speed and offer more storage capacity than flash memory cells
, the current industry standard.
Long-lived sentries called memory cells
remain ready to pounce if the bug reappears.
It was designed with the help of mathematical simulations specifically for use in phase-change memory cells
Earlier research showed humans having cross-reactive memory cells
to a wide range of H5N1 peptides despite any previous exposure to avian influenza A (H5N1).
To create so-called nonvolatile electronic memory, the researchers built one-bit, prototype memory cells
from layers of metal and semiconductors, manipulating the energy barriers that appear naturally at the interfaces.
