Networking

The SRAMs Required by Modern Systems Must Have High Reliability

3a

Military and Avionics Signal Processing and Computing

Modern systems need error-free, high-performance Synchronous SRAMs Systems running mission-critical applications need memories with a high RTR1 and zero system errors

Data in traditional SRAMs is corrupted by Soft Errors2 caused by background radiation

Soft Errors in SRAMs cause functional failures that lead to system downtime

1 Random Transaction Rate: The maximum rate of truly random accesses to memory, expressed in transactions per second (MT/s, GT/s)2 A data error that results in the state (Logic 1 or Logic 0) of SRAM memory cells being flipped3 Error-Correcting Code: A method of encoding and decoding a bit stream with extra bits to detect and correct bit errors

Cypress Is the SRAM Market LeaderCypress is a preferred SRAM supplier to all major network equipment providers with: More than 2.7 billion cumulative units shipped

49%1 market share for Synchronous SRAM products

Cypress has the broadest Synchronous SRAM portfolio and offers:More than 2,300 Synchronous SRAM products

Standard Sync SRAMs and No Bus Latency™ (NoBL™)2 SRAMs with densities from 2Mb to 72Mb

Four generations of QDR®3 SRAMs with densities from 18Mb to 144Mb

And, now, Synchronous SRAMs with on-chip ECC and 0.01-FIT/Mb4 reliability

Cypress is the most dependable Synchronous SRAM supplier with: Lead times of ≤6 weeks with >99% on-time delivery

Multiple qualified fabs, assembly sites and test sites

Legacy product support for up to 20 years

1 2014 Gartner and WSTS market research reports estimated for Synchronous SRAM products2 A Synchronous SRAM that transfers data on the rising edge of the clock signal with either a one (Standard Sync) or zero (NoBL™) clock cycle delay between read and write operations3 Quad Data Rate: A synchronous SRAM with two ports, each of which transfers data on both the rising and falling edges of a clock signal4 The projected failure rate of a device; one FIT/Mb equals one failure per billion device hours per megabit of data

Terms You Will Hear Today Synchronous SRAMAn SRAM device in which read or write operations are synchronized with one or more external clocks

Standard Sync SRAM and No Bus Latency™ (NoBL™)A Synchronous SRAM that transfers data on the rising edge of the clock signal with either one (Standard Sync) or zero (NoBL) clock cycle delay between read and write operations

Flow-Through and Pipeline ModesModes of Synchronous SRAM operation that optimize either read latency (Flow-Through) or operating frequency (Pipeline)

Soft ErrorA data error caused by background radiation

Soft Error Rate (SER)The rate at which a device is predicted to have Soft Errors

Error-Correcting Code (ECC)Data encoded with extra “parity” bits to detect and correct bit errors

Failures-in-Time (FIT) per Megabit of Data (FIT/Mb) The projected failure rate of a device

One FIT/Mb equals one failure per billion device hours per megabit of data

Random Transaction Rate (RTR)The maximum rate of truly random accesses to memory, expressed in transactions per second (MT/s, GT/s)

Memories with higher RTR enable proportionally higher processing rates

Restriction of Hazardous Substances (RoHS)A European Union directive intended to eliminate the use of environmentally hazardous material in electronic components

Standard SRAMs without ECC cannot achieve FIT rates of <10 FIT/Mb Today's Synchronous SRAMs have FIT rates of 150-1,500 FIT/Mb

Correcting Soft Errors with a system-level ECC solution forces undesirable system design trade-offsSystem-level error detection and correction increase design complexity and cycle time

These solutions require additional memory and error-correction chips, increasing board space and cost

Systems require memories with both high performance and low power consumption10-Gbps to 20-Gbps1 network switches and routers require memory solutions with RTRs of 120 MT/s to 240 MT/s, respectively

A 72Mb Standard Sync/NoBL SRAM without ECC that has an RTR of 250 MT/s consumes 1.65 W of active power

Cypress Synchronous SRAMs with on-chip ECC solves these problems:Ensures a FIT rate of <0.01 FIT/Mb that is 1,000x lower than a standard SRAM without ECC

Offers pin-to-pin compatibility with Cypress’s existing products to simplify design

Provides an RTR of 250 MT/s with an active power consumption of 1.05 W

Cypress’s Synchronous SRAMs with on-chip ECC provide low-power, error-free memory solutions for systems that require high performance and high reliability
