Features

Clocking and Addressing Schemes

• 2.5 Clock Latency

The GS8672D20/38AE SigmaQuad-II+ ECCRAMs are

synchronous devices. They employ two input register clock

inputs, K and K. K and K are independent single-ended clock

inputs, not differential inputs to a single differential clock input

buffer.

• On-Chip ECC with virtually zero SER

• Simultaneous Read and Write SigmaQuad™ Interface

• JEDEC-standard package

• Dual Double Data Rate interface

• Byte Write Capability

• Burst of 4 Read and Write

• On-Die Termination (ODT) on Data (D), Byte Write (BW),

and Clock (K, K) outputs

Because Separate I/O SigmaQuad-II+ B4 RAMs always

transfer data in four packets, A0 and A1 are internally set to 0

for the first read or write transfer, and automatically

• 1.8 V +100/–100 mV core power supply

• 1.5 V HSTL Interface

• Pipelined read operation

• Fully coherent read and write pipelines

• ZQ pin for programmable output drive strength

• IEEE 1149.1 JTAG-compliant Boundary Scan

• Pin-compatible with 144Mb and future 288Mb devices

• 165-bump, 15 mm x 17 mm, 1 mm bump pitch BGA package

• RoHS-compliant 165-bump BGA package available

incremented by 1 for the next transfers. Because the LSBs are

tied off internally, the address field of a SigmaQuad-II+ B4

RAM is always two address pins less than the advertised index

depth (e.g., the 4M x 18 has a 1M addressable index).

On-Chip Error Correction Code

GSI's ECCRAMs implement an ECC algorithm that detects

and corrects all single-bit memory errors, including those

induced by Soft Error Rate (SER) events such as cosmic rays,

alpha particles. The resulting SER of these devices is

anticipated to be <0.002 FITs/Mb — a 5-order-of-magnitude

improvement over comparable SRAMs with no On-Chip ECC,

which typically have an SER of 200 FITs/Mb or more. SER

quoted above is based on reading taken at sea level.

SigmaQuad™ ECCRAM Overview

The GS8672D20/38AE are built in compliance with the

SigmaQuad-II+ ECCRAM pinout standard for Separate I/O

synchronous ECCRAMs. They are 75,497,472-bit (72Mb)

ECCRAMs. The GS8672D20/38AE SigmaQuad ECCRAMs

are just one element in a family of low power, low voltage

HSTL I/O ECCRAMs designed to operate at the speeds needed

to implement economical high performance networking

systems.

However, the On-Chip Error Correction (ECC) will be

disabled if a “Half Write” operation is initiated. See the Byte

Write Contol section for further information.
