molex introduces fcram* memory socket for high performance networking systems. fcram* (fast cycle random access memory ) is a new technology that evolved from dram core architecture, creating memory products with sram-like performance with dram technology. fcra m improves performance by using a proprietary pipeline operation and hidden pre-charge to reduce the random access cycle time to less than half of today's fastest sdram, rambus and ddr memory technologies. in addition, fcram's highly segmented memory core uses less than half the power of sdram within the same effective bus bandwidth. molex?s fcram socket allows savings on pc b real estate due to its small size pitch. it?s narrow body design enables ease on smt tail?s inspection and rework. the robust latches at both ends with grippers offers safe locking of memory modules to the connector socket, and reduces micro-motion at the same time. molex is an active member of jedec work group which defines standards for the memory industry. like molex?s other memory socket connector, the fcram socket conforms to jedec memory socket specif ications, comes in lead free plating and is rohs compliant. * fcram is a trademark of fujitsu ltd. 0.6mm (.0236?) pitch fcram *socket features and specifications 87901 vertical, smt features and benefits ? small footprint reduces utilization of pcb real estate ? small form factor allows to fit in slim enclosure ? surface mount technology enables easy processing and utilization of both sides of pcb ? solder pads at both ends of housing provide additional mechanical strength after soldering ? robust dual latches provide excellent module retention and easy ejection of module ? polarization key ensures cor r ect module orientation ? pick-and-place cap allows automa tic pcba mounting and processing ? wide end body design provides stability during smt proces s ? narrow body with step allows ease of inspection and rework on smt tails ? grippers feature reduces micro-mo tion and provide a secure mating grippers pick and place cap step on the narrow body allows ease on inspection and rework of smt tails wide end for stability narrow body
