SRAM Clocking Scheme QDR SRAMs are high performance networking SRAMs introduced by the QDR consortium comprised of Cypress, IDT and Micron. The Clocking Structure of the QDR is different from those of traditional SRAMs. The QDR SRAM is a high performance SRAM that has been introduced by the QDR consortium comprised of Cypress, IDT and Micron. This application note introduces the reader to a QDR memory controller designed using the Xilinx Spartan-II FPGAs. As computing devices have progressed, so also has the portability of these computing devices.
Portable devices call for a lot of features from the constituent components.
These include power consumption, device size, etc. This application note also describes a typical application of Low Power SRAMs and then gives the designer a feel of the power saving by using a MoBL device in the same. The Fast SRAM Architecture Processors in high performance PCs, workstations, communication equipment, and network applications demand high speed memories. The type of memory required is determined by the system architecture, the application and the processor used. System performance will suffer if the memory sub-system cannot satisfy the processor requirements.
