SigmaCIOFamily Overview  
Clocking and Addressing Schemes  
The GS8662T19/37AE are built in compliance with the  
SigmaCIO DDR-II+ SRAM pinout standard for Common I/O  
synchronous SRAMs. They are 75,497,472-bit (72Mb)  
SRAMs. The GS8662T19/37AE SigmaCIO SRAMs 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.  
The GS8662T19/37AE SigmaCIO DDR-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.  
Common I/O x36 and x18 SigmaCIO DDR-II+ B2 RAMs  
always transfer data in two packets. When a new address is  
loaded, A0 presets an internal 1 bit address counter. The  
counter increments by 1 (toggles) for each beat of a burst of  
two data transfer.  
Common I/O x8 SigmaCIO DDR-II+ B2 RAMs always  
transfer data in two packets. When a new address is loaded,  
the LSB is internally set to 0 for the first read or write transfer,  
and incremented by 1 for the next transfer. Because the LSB  
is tied off internally, the address field of a x8 SigmaCIO DDR-  
II+ B4 RAM is always one address pin less than the advertised  
index depth (e.g., the 4M x 18 has a 2048K addressable index).
