The majority of digital systems, including computers, mobile phones and smart TVs use memory cells
for data storage and data recovery.
Chang, Yeo and colleagues discovered that the decision by an individual T cell to produce effector and memory cells
is made almost at the moment of infection.
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.
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.
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.
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).
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
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.
