SigmaRAM™ Family Overview
GS8342S08/09/18/36AE are built in compliance with the
SigmaSIO-II SRAM pinout standard for Separate I/O
synchronous SRAMs. They are 37,748,736-bit (36Mb)
SRAMs. These are the first in a family of wide, very low
voltage HSTL I/O SRAMs designed to operate at the speeds
needed to implement economical high performance
networking systems.
Clocking and Addressing Schemes
A Burst of 2 SigmaSIO-II SRAM is a synchronous device. It
employs dual input register clock inputs, K and K. The device
also allows the user to manipulate the output register clock
input quasi independently with dual output register clock
inputs, C and C. If the C clocks are tied high, the K clocks are
routed internally to fire the output registers instead. Each Burst
of 2 SigmaSIO-II SRAM also supplies Echo Clock outputs,
CQ and CQ, which are synchronized with read data output.
When used in a source synchronous clocking scheme, the Echo
Clock outputs can be used to fire input registers at the data’s
destination.
Because Separate I/O Burst of 2 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 Burst of 2 RAM is always one address pin less than
the advertised index depth (e.g., the 2M x 18 has a 1M
addressable index).
