Cypress Semiconductor Corp. announced it is supplying a CMOS image sensor for InPhase Technologies Inc.'s Tapestry holographic data storage system.

The companies have collaborated since 2005 to develop an ultrasensitive and ultrafast CMOS image sensor to meet the high-speed reading of data recorded by InPhase's Tapestry drive. The Cypress CMOS imager features a digital interface and is sized with a pixel count of 1696-by-1710 and a pixel pitch of 8?m. The imager enables data to be read at 500fps.

Holographic storage delivers high capacity by recording data throughout the volume of the recording material, and not just on the surface. With each flash of the laser, a data page of approximately 1 million bits is recorded. Each data page is located at a unique address within the material and several hundred pages of data, each with their own unique address, are recorded in the same location of the medium. Each of these collections of data pages is then referred to as a "book." This new recording technique enables more holograms to be stored in the same volume of material by overlapping not only pages, but also books of data. This dramatically increases the storage density.

"Cypress's imaging expertise was critical to the development of our holographic drive," said Nelson Diaz, CEO of InPhase. "We have largely redefined how information is stored and read for next generation recording devicesand Cypress has played a significant role in that endeavor."

"The next generation of imaging products will require massive amounts of storage in small form factors," said Cliff Drowley, VP for Cypress's image sensor business unit. "The consumer and professional imaging worlds are converging, and higher-yield, lower-cost products are required to continue the progress of optical recording. The InPhase Tapestry drive is a seminal touchpoint in this delicate area of technical development."
