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.
Clocking and Addressing Schemes 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...
