SigmaCIO™ Family Overview
The GS8342T08/09/18/36AE are built in compliance with the
SigmaCIO DDR-II SRAM pinout standard for Common I/O
synchronous SRAMs. They are 37,748,736-bit (36Mb)
SRAMs. The GS8342T08/09/18/36AE 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.
Clocking and Addressing Schemes
The GS8342T08/09/18/36AE 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

clock inputs, not differential inputs. If the C clocks are tied
high, the K clocks are routed internally to fire the output
registers instead.
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 8M x 8 has a 2M addressable index).
