Features  
Clocking and Addressing Schemes  
• 2.0 Clock Latency  
The GS8672Q19/37BE 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 pinout and package  
• Dual Double Data Rate interface  
• Byte Write Capability  
• Burst of 2 Read and Write  
• On-Die Termination (ODT) on Data (D), Byte Write (BW),  
and Clock (K, K) outputs  
• 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 18Mb, 36Mb and 144Mb devices  
• 165-bump, 15 mm x 17 mm, 1 mm bump pitch BGA package  
• RoHS-compliant 165-bump BGA package available  
Each internal read and write operation in a SigmaQuad-II+ B2  
ECCRAM is two times wider than the device I/O bus. An input  
data bus de-multiplexer is used to accumulate incoming data  
before it is simultaneously written to the memory array. An  
output data multiplexer is used to capture the data produced  
from a single memory array read and then route it to the  
appropriate output drivers as needed. Therefore the address  
field of a SigmaQuad-II+ B2 ECCRAM is always one address  
pin less than the advertised index depth (e.g., the 4M x18 has  
an 2M 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 ECCRAMs 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.  
SigmaQuadECCRAM Overview  
The GS8672Q19/37BE 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 GS8672Q19/37BE 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.
