SigmaCIOFamily Overview  
clock inputs, not differential inputs. If the C clocks are tied  
high, the K clocks are routed internally to fire the output  
registers instead.  
The GS81302T08/09/18/36E are built in compliance with the  
SigmaCIO DDR-II SRAM pinout standard for Common I/O  
synchronous SRAMs. They are 150,994,944-bit (144Mb)  
SRAMs. The GS81302T08/09/18/36E 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.  
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.  
Clocking and Addressing Schemes  
The GS81302T08/09/18/36E 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. The device also allows the user to manipulate the  
output register clock inputs quasi independently with the C and  
C clock inputs. C and C are also independent single-ended  
Common I/O x8 and x9 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/x9 SigmaCIO  
DDR-II B4 RAM is always one address pin less than the  
advertised index depth (e.g., the 16M x 8 has a 8M addressable  
index).
