Cypress Semiconductor Corp. announced the addition of wafer products to its nonvolatile random access memory (NVRAM) portfolio. Cypress's NVRAM portfolio, which includes Ferroelectric-RAM and nonvolatile static RAM devices, offers reliable protection of critical data during a power failure.

Many mission-critical applications that require the unique benefits of F-RAM and nvSRAM also require bare die for small or unique packaging options. Cypress F-RAM is the most energy-efficient NVRAM technology in the industry with a virtually unlimited 100 trillion write cycle endurance. The ferroelectric material in F-RAM memory cells is highly resistant to data corruption caused by radiation or magnetic field exposure, providing soft error rate immunity for medical, aerospace and defense applications.

Cypress nvSRAM is the fast NVRAM technology in the industry, with access times as low as 20 ns. It provides nonvolatile data retention without the need for additional batteries and also provides unlimited endurance. Cypress offers a broad portfolio of F-RAM products with densities from 4Kb to 4Mb and supply voltages from 2.0V to 5.5V.

Cypress F-RAMs feature virtually unlimited endurance of one-hundred trillion read and write cycles, making them an ideal solution for write-intensive applications. F-RAM is the industry's most energy efficient nonvolatile RAM solution; the F-RAM cell is inherently low power and operates without a charge pump. Cypress F-RAM is an ideal solution for applications requiring high-performance, high-reliability, low-cost nonvolatile memory solutions, including automotive, industrial, computing, networking, smart meter, and multifunction printer applications.

Cypress's nvSRAMs use charge stored on an external capacitor instead of a battery, making the devices compatible with standard PCB assembly processes. Cypress's nvSRAMs are ROHS-compliant and directly replace SRAM and battery-backed SRAM (BBSRAM) products, offering fast non-volatile data storage. Data transfers from the SRAM to the device's nonvolatile elements take place automatically at power down.

On power up, data is restored to the SRAM from the nonvolatile memory. In networking, industrial, computing and RAID applications, nvSRAMs offer high-speed data transfer while ensuring data integrity in case of power outages, without the need for a battery. Cypress supports wafer products in 256Kb to 4Mb F-RAM densities and 1Mb to 16Mb nvSRAM densities for select customers.
