The MB814405D-60PJN is a high-performance EDO (Extended Data Output) DRAM module from Fujitsu, designed to enhance the speed and efficiency of data access and transfer. Featuring a capacity of 4Mbits arranged in a 1Mx4 configuration and operating at 5V, this DRAM module is encapsulated in a SOJ (Small Outline J-leaded) package. EDO memory technology, being an advancement over conventional FPM (Fast Page Mode) DRAM, provides a significant boost in processing speeds by allowing a new data access cycle to start while the previous one is still in the output stage. This drastic improvement in access time made EDO DRAM like the MB814405D-60PJN particularly popular in systems where higher bandwidth and lower latency were crucial. It found applications in various computing environments including servers, workstations, and personal computers of its era, offering reliable, high-speed memory solutions.
