Low Power SRAMs
Jump to Page Section:
The recent demands for highly secure and reliable user systems are driving increased demand for highly reliable SRAM, which is used to store important information such as system programs and financial transaction data. Renesas' Low Power SRAM (LPSRAM) products have a proven track record for application in middle- to small-scale memory systems and are designed to provide enhanced reliability and longer backup battery life for applications such as factory automation (FA), industrial equipment, and the smart grids.
Renesas' Advanced Low Power SRAMs, the core products series, have acquired a solid reputation for achieving both high-performance and high-reliability without any technical trade-off. These advanced LPSRAM devices feature exclusive technology in their memory cells that achieves soft error resistance over 500 times that of conventional Full CMOS memory cells. This makes them desirable for use in fields requiring high reliability.
