The Texas Instruments SMJ44C256-15FQMT is a 1-Megabit Fast Page Mode DRAM organized as 256K words by 4 bits. This MOS technology component features a maximum access time of 150 ns and supports CAS BEFORE RAS REFRESH functionality. Operating asynchronously, it is designed for a supply voltage range of 4.5V to 5.5V, with a nominal 5V requirement. The device is housed in a 20-terminal CDSO (Ceramic Dual Small Outline) package, specified by JESD-30 code R-CDSO-N20. Its construction with ceramic, metal-sealed cofired material and its MIL-PRF-38535 screening level indicate suitability for demanding applications. This component is prevalent in aerospace, defense, and industrial sectors requiring high reliability and robust performance. The SMJ44C256 series offers efficient memory solutions for these critical systems.
