A novel type of computer memory could, in theory, let you store tens or even hundreds of times as much data on your smartphone. Researchers at Rice University have demonstrated a more practical way to manufacture it.
The type of memory in question, resistive random access memory (RRAM), is being developed by several companies, but fabrication usually requires high-temperatures or voltages, making production difficult and expensive. The Rice researchers have shown a way to make RRAM at room temperature and with far lower voltages.
Like flash memory, RRAM can store data without a constant supply of power. Whereas flash memory stores bits of information in the form of charge in transistors, RRAM stores bits using resistance. Each bit requires less space, increasing the amount of information that can be stored in a given area.
What’s more, it should be easier to stack up layers of RRAM, helping to further increase the amount of information that can be packed onto a single chip. RRAM can also operate a hundred times faster than flash. Some prototypes can store data densely enough to enable a terabyte chip the size of a postage stamp.
