Rewriting Codes for Flash Memories [PDF]

IEEE Transactions on Information Theory, 2014
Flash memory is a non-volatile computer memory comprising blocks of cells, wherein each cell can take on q different values or levels. While increasing the cell level is easy, reducing the level of a cell can be accomplished only by erasing an entire block.

Hiding Information in Flash Memory [PDF]

2013 IEEE Symposium on Security and Privacy, 2013
This paper introduces a novel information hiding technique for Flash memory. The method hides data within an analog characteristic of Flash, the program time of individual bits. Because the technique uses analog behaviors, normal Flash memory operations are not affected and hidden information is invisible in the data stored in the memory.

Neuromorphic Optical Tracking and Imaging of Randomly Moving Targets Through Dynamic Dense Scattering Media

Advanced Science, EarlyView.
Vision begins not with images but with change: the retina fires only when something moves, handing the brain a stream of spikes. A neuromorphic imaging system adopts the same strategy—an event sensor that sees like the retina, a spiking network that thinks like the brain—to track and reconstruct fully randomly moving targets through tissue (phantom ...
