1.8 V and 1.5 V I/O
The GS8342Q08/09/18/36BD 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. 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.
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 4M x 8 has an 2M addressable
index).
SigmaQuad™ Family Overview
The GS8342Q08/09/18/36BD are built in compliance with the
SigmaQuad-II SRAM pinout standard for Separate I/O
synchronous SRAMs. They are 37,748,736-bit (36Mb)
SRAMs. The GS8342Q08/09/18/36BD SigmaQuad 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.
