This forms a unit of memory, or bit, at each junction. The scientists managed to make the most dense unit yet, a 160 kilobit memory cell with a bit density of 100 gigabits per square centimetre.

The computer has 31 instructions and 240 words of program memory (a word is a 4-bit memory location). There are also 16 words of user memory for data input and manipulation.

In a 4 bit memory cell (16 current levels), for example, a one order of magnitude difference between each level is not achievable, because this would mean a switching ratio as high as 10 15.

Two teams of researchers independently found the newly identified brain-cell circuit when studying rodents’ ability to recall a fear memory. The circuit that initially recalled the memory ...

Spansion, the memory products manufacturer, has demonstrated four-bit-per-cell Flash memory for the first time. The Silicon Valley-based vendor intends its so-called MirrorBit Quad technology to ...

A computational model explains how place cells in the hippocampus can be recruited to form any kind of episodic memory, even when there's no spatial component. Nearly 50 years ago, neuroscientists ...
