SigmaQuad-IIIeFamily Overview
SigmaQuad-IIIe ECCRAMs are the Separate I/O half of the
SigmaQuad-IIIe/SigmaDDR-IIIe family of high performance
ECCRAMs. Although very similar to GSI's second generation
of networking SRAMs (the SigmaQuad-II/SigmaDDR-II
family), these third generation devices offer several new
features that help enable significantly higher performance.
Clocking and Addressing Schemes
The GS81313LD18/36GK SigmaQuad-IIIe ECCRAMs are
synchronous devices. They employ three pairs of positive and
negative input clocks; one pair of master clocks, CK and CK,
and two pairs of write data clocks, KD[1:0] and KD[1:0]. All
six input clocks are single-ended; that is, each is received by a
dedicated input buffer.
CK and CK are used to latch address and control inputs, and to
control all output timing. KD[1:0] and KD[1:0] are used solely
to latch data inputs.
Each internal read and write operation in a SigmaQuad-IIIe B4
ECCRAM is four 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-IIIe B4 ECCRAM is always two address
pins less than the advertised index depth (e.g. the 8M x 18 has
2M addressable index).
On-Chip Error Correction Code
GSI's ECCRAMs implement an ECC algorithm that detects
and corrects all single-bit memory errors, including those
induced by SER events such as cosmic rays, alpha particles,
etc. The resulting Soft Error Rate of these devices is
anticipated to be <0.002 FITs/Mb — a 5-order-of-magnitude
improvement over comparable SRAMs with no on-chip ECC,
which typically have an SER of 200 FITs/Mb or more.
All quoted SER values are at sea level in New York City.
