SigmaQuad Family Overview
The GS8342QT07/10/19/37BD 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 GS8342QT07/10/19/37BD 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 GS8342QT07/10/19/37BD 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.
Because Separate I/O SigmaQuad-II+ B2
RAMs always
transfer data in two packets, A0 is internally set to 0 for the
first read or write transfer, and automatically incremented by 1
for the next transfer. Because the LSB is tied off internally, the
address field of a SigmaQuad-II+ B2
RAM is always one
address pin less than the advertised index depth force return
(e.g., the 2M x 18 has a 1M addressable index).
