According tho this post, HP plans to introduce the first commercial product based on memristor memory in three years. In case you wonder: no, it won't be a USB brain. According to Technology Review, it will be a flash memory.
Why flash memory? This storage suffer from some of the same limitations that plague silicon transistors: the limited amount of data-writing cycles, and the physical limits that prevent increasing storage in dense memory devices. Memristor memory can withstand up to about a million read-write cycles in lab tests, and can achieve densities unreachable by conventional technologies currently employed to build flash memory devices.

Memristors is not a solo business. In a recent SyNAPSE-centric meeting,
