Clocking and Addressing Schemes
The GS8342TT06/11/20/38BD SigmaDDR-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 SigmaDDR-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
SigmaDDR-II+ B2 RAM is always one address pin less than
the advertised index depth (e.g., the 4M x 8 has a 2M
addressable index).
SigmaDDR-II™ Family Overview
The GS8342TT06/11/20/38BD are built in compliance with
the SigmaDDR-II+ SRAM pinout standard for Common I/O
synchronous SRAMs. They are 37,748,736-bit (36Mb)
SRAMs. The GS8342TT06/11/20/38BD SigmaDDR-II+
