SigmaQuadFamily Overview
The GS81302Q07/10/19/37E are built in compliance with the
SigmaQuad-II+ SRAM pinout standard for Separate I/O
synchronous SRAMs. They are 150,994,944-bit (144Mb)
SRAMs. The GS81302Q07/10/19/37E 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.
Clocking and Addressing Schemes
The GS81302Q07/10/19/37E 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.
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 16M x 8 has an 8M
addressable index).

Notes:
1. NC = Not Connected to die or any other pin
2. When ZQ pin is directly connected to VDDQ, output impedance is set to minimum value and it cannot be connected to ground or left
unconnected.
3. K and K cannot be set to VREF voltage.
