About the Memory Products Division | Cypress Semiconductor
By delivering the broadest portfolio of high-performance memories for embedded systems, Cypress has established itself as the marketshare leader in SRAM, and NOR Flash memories that form the brains of today's most advanced embedded systems. The memory product portfolio includes the world's highest throughput QDR®-IV SRAMs, low-power MoBL® SRAMs, high-performance serial and parallel NOR Flash memories and high-reliability F-RAM™ ferroelectric memory devices that capture and protect the world's most-critical data. Cypress's industry-leading HyperFlash™ memories deliver 333 megabytes per second read throughput-more than five times faster than traditional Quad SPI flash, and one-third the number of pins of parallel NOR flash.
The following table summarizes the markets and applications related to our products in this segment:
Asynchronous SRAMs. We manufacture a wide selection of fast asynchronous and micropower SRAMs with densities ranging from 16 Kbits to 64 Mbits. These memories are available in many combinations of bus widths, packages and temperature ranges including automotive. They are ideal for use in point-of-sale terminals, gaming machines, network switches and routers, IP phones, IC testers, DSLAM Cards and various automotive applications. In 2010, Cypress introduced the market’s first 32-bit and 64-bit fast asynchronous SRAMs targeting storage servers, switches, routers, test and military equipment.
Synchronous SRAMs. Our high-speed synchronous SRAMs include standard synchronous pipelined, No Bus Latency ("NoBL"), Quad Data Rate, and Double Data Rate SRAMs, and are typically used in networking applications. NoBL synchronous SRAMs are optimized for high-speed applications that require maximum bus bandwidth up to 250 MHz, including those in the networking, instrumentation, video and simulation businesses. Double Data Rate ("DDR") SRAMs target network applications and servers that operate at data rates up to 550 MHz. Quad Data Rate™ ("QDR"®) products are targeted toward next-generation networking applications, particularly switches and routers that operate at data rates beyond 550 MHz and offer twice the bus bandwidth of DDR SRAMs. In 2011, Cypress introduced the industry's first 65-nm QDR and DDR SRAMs. The 144-Mbit and 72-Mbit devices, developed with foundry partner UMC, feature the industry's fastest clock speeds and operate at half the power of their 90-nm predecessors. They are ideal for networking, medical imaging and military signal processing.
nvSRAMs. nvSRAMs are products that operate similar to standard asynchronous SRAM and reliably store data into an internal nonvolatile array during unanticipated power downs. The competitive advantage of an nvSRAM is infinite endurance and much faster read/write speed than a serial flash or EEPROM. Additionally, these high-speed nonvolatile SRAM devices can store data for more than 20 years without battery backup. These memories are ideal for redundant array of independent disks ("RAID") storage arrays, metering applications, multifunction printers and other industrial applications, such as PLCs. Additionally, we have our 1-Mbit serial nonvolatile SRAM family and our 4-Mbit and 8-Mbit parallel nvSRAMs with an integrated real-time clock, providing failsafe battery-free data backup in mission-critical applications.
Programmable Clocks. Programmable timing solutions such as our InstaClock device combine high performance with the flexibility and fast time to market of field-programmable devices at a cost that is competitive against custom clocks at equivalent volumes. Working with our easy-to-use CyberClocks software, designers can optimize device parameters such as drive strength, phased-lock loop bandwidth and crystal input capacitive loading. Our programmable clocks are ideal for devices requiring multiple frequencies including Ethernet, PCI, USB, HDTV, and audio applications. Additionally, the FleXO™ family of high-performance clock generators can be instantly programmed in the factory or field to any frequency up to 650 MHz, accelerating time to market and improving manufacturing quality.
RoboClock Clock Buffers. Our RoboClock family of clock buffers feature programmable output skew, programmable multiply/divide factor, and user-selectable redundant reference clocks that provide fault tolerance. Designers can control output skew and multiply and divide factors to help accommodate last-minute design changes. RoboClock offers a high-performance timing solution for designers of communications, computation and storage networking applications.
FIFO Memories. FIFOs are used as a buffer between systems operating at different frequencies. Our high-performance FIFO products provide the ideal solution to interconnect problems such as flow control, rate matching, and bus matching. Our FIFO portfolio is comprised of more than 100 synchronous and asynchronous memories in a variety of speeds, bus widths, densities and packages. Using industry-standard pinouts, these products are easily integrated into new and existing designs. Unidirectional, bidirectional, tri-bus and double sync configurations are available with built-in expansion logic and message-passing capabilities for various markets including video, data communications, telecommunications and network switching/routing. In 2011, Cypress introduced the industry's highest density FIFOs at 72 Mbits.
Dual-Port Memories. Dual ports, which can be accessed by two different processors or buses simultaneously, target shared-memory and switching applications, including networking switches and routers, cellular base stations, mass-storage devices and telecommunications equipment. We offer a portfolio of more than 160 synchronous and asynchronous dual-port interconnects ranging in densities from 8 Kbits to 36 Mbits with speeds of up to 250 MHz. Our dual ports are the compelling solutions for interprocessor communication in a broad range of applications. For high-volume multiprocessor applications (wireless handsets, PDAs, consumer) we offer the MoBL dual port, providing a low cost, quick time-to-market interconnect solution with the industry's lowest power-consumption.
