Innovative Silicon takes $25M for ultra-dense memory

If you’re not reaching, engaging, and monetizing customers on mobile, you’re likely losing them to someone else. Register now for the 8th annual MobileBeat, July 13-14, where the best and brightest will be exploring the latest strategies and tactics in the mobile space.

Innovative Silicon is the developer of Z-RAM, which the company claims has a higher density than DRAM or SRAM. All are different types of random-access memory, a fast form of memory used for temporary storage of information during computer processing functions.

The density of Z-RAM could make it a better choice for use in portable electronics. Innovative Silicon also says its technology is very low in cost. It has so far struck licensing deals with Hynix Semiconductor, a DRAM maker, and AMD, Intel’s major chip-making competitor.

The $25 million investment was led by Wellington Partners Venture Capital, joined by the investors of the first two rounds. The company is based in Santa Clara, Calif., but also has facilities in Japan and Switzerland.
