Military Temp  
1.8 V V  
DD  
1.8 V and 1.5 V I/O  
are just one element in a family of low power, low voltage  
HSTL I/O SRAMs designed to operate at the speeds needed to  
implement economical high performance networking systems.  
Features  
• Military Temperature Range  
• 2.0 Clock Latency  
• Simultaneous Read and Write SigmaQuad™ Interface  
• JEDEC-standard pinout and package  
• Dual Double Data Rate interface  
Clocking and Addressing Schemes  
• Byte Write controls sampled at data-in time  
• On-Die Termination (ODT) on Data (D), Byte Write (BW),  
and Clock (K, K) inputs  
• Burst of 2 Read and Write  
• 1.8 V +100/–100 mV core power supply  
• 1.5 V or 1.8 V HSTL Interface  
The GS8662Q07/10/19/37BD SigmaQuad-II+ SRAMs 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.  
• Pipelined read operation  
Each internal read and write operation in a SigmaQuad-II+ B2  
RAM 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 RAM is always one address pin less than  
the advertised index depth (e.g., the 8M x 8 has an 4M  
addressable index).  
• Fully coherent read and write pipelines  
• ZQ pin for programmable output drive strength  
• Data Valid Pin (QVLD) Support  
• IEEE 1149.1 JTAG-compliant Boundary Scan  
• 165-bump, 13 mm x 15 mm, 1 mm bump pitch BGA package  
SigmaQuadFamily Overview  
The GS8662Q07/10/19/37BD are built in compliance with the  
SigmaQuad-II+ SRAM pinout standard for Separate I/O  
synchronous SRAMs. They are 75,497,472-bit (72Mb)  
SRAMs. The GS8662Q07/10/19/37BD SigmaQuad SRAMs
