Simtek's STK14EC8 (512Kbit x 8) and STK14EC16 (256Kbit x 16) devices deliver fast access SRAM performance at speed grades of 15, 25, and 45ns while offering highly reliable and transparent non-volatile backup on any power disruption. The new 4Mbit devices combine Simtek's expertise in nvSRAM design with Cypress Semiconductor's SONOS fabrication expertise and are the result of a joint development agreement announced in March 2006.
"Moving to 130nm and 4Mbit densities is a big milestone on nvSRAM's path to even better access speeds and performance within the same package footprints and power budgets," said Harold Blomquist, CEO and president at Simtek. "The new 4Mbit density will grant nvSRAM a greater role in the system's integrated memory hierarchy. Our 130nm designs give customers larger nvSRAM's at attractive price points and fill an increasingly important market need. Our collaboration with Cypress has created the best 'fast access' SRAM memory solution in the world where non-volatile back-up is demanded."

-- Single 3.3V Power Supply
The unmatched fast access times and unlimited read/write SRAM performance combined with high reliability SONOS non-volatile storage makes nvSRAM the solution of choice in many applications. nvSRAM devices emulate and replace fast SRAM in high-speed processor systems to reduce wait states and optimize performance, while also delivering the added benefit of backup protection for critical state information. Used for decades in military, industrial, medical, automotive, and computer markets, nvSRAM devices now also have migrated to RAID write journals, robotic axis tracking, and medical datalogging, and at 4, 8, and 16Mbit sizes, will also see more general applications as a total system cache memory. The first applications for 4 Mbit products will likely be large industrial control and managed robotic systems where high-volume status and positioning information are tracked and maintained. nvSRAM is also very popular in direct attach RAID servers, where the larger density nvSRAMs will allow expanded use of the technology there as well. Designers have also shown interest in the 4Mbit densities for various data logging functions in medical equipment, security systems, automobiles, etc.
The STK14EC8 is available in both the 44-pin thin small outline package II (TSOPII) and 48-pin ball grid array (BGA) packages. The STK14EC16 is available in the 44 and 54-pin TSOPII, as well as the 48-pin BGA package.
1,000-unit pricing for each product is $18.50 US. Both products are being sampled now and are scheduled for a production ramp in the first calendar quarter of 2008.
