Current Space systems are designed with integrated circuitry fabricated on technology nodes several generations behind their Commercial counterparts. Space community is facing a huge initiative to bring their electronic designs into the 21^* century. Cypress has introduced Radiation Hardened QDRI1+ products to the Space market. It is the highest performance and highest density Radiation Hardened SRAM memory available (4X better than the competition]. However, interface support for 72Mbit RHQDR1I+ does not exist. Besides RHQDRII+, the Space community is also looking for higher densities/performance of all system memory types - Single Ports, Dual Ports & FIFOs. Through this invention, the 72Mbit RHQDRII+ can be used in all three memory types and leap frog the competition in performance. Cypress"s RHQDRI1+ is the highest performance and highest Radiation Hardened SRAM available. However, QDR architecture requires an interface controller due to the Double Data Rate architecture. Incorporating different memory functionalities in the interface controller allows usage of the RHQDRII+ as different memory types -Single Port, Dual Port and FIFO. Another important SPACE System design requirement is component qualification. With the multi-use controller interface, the Space designers only need to qualify RHQDR11+ and use it in all applications.
