Quad SRAMs

GSI's SigmaQuad SRAMs are the acknowledged leader in the industry with their combination of capacity and performance. SigmaQuad transaction rates are unequaled by any competitors.


SigmaQuad SRAMs are synchronous memories with separate read and write data buses. “Quad” refers to their ability to transfer 4 beats of data (2 beats per data bus) in a single clock cycle. SigmaQuad memories are ideal for applications that alternate between read and write operations frequently, at operating speeds of 250 MHz and above.


GSI’s SigmaQuad devices are compatible with all competitor Quad Data Rate SRAMs.
