PRN128M16V89CG8GNF-15E SPECTEK DDR3 128*16 原装现货

GENERAL DESCRIPTION 

ThePRN256M8V89CG8GQF-15Eand the  PRN128M16V89CG8GNF-15Eishigh performance  dynamicrandom-access 2Gb device respectively. These components areorganized in a x8 configuration, and  utilize 8 bankarchitecture with a synchronous DDR3  interface.These DDR3 SDRAM components use double  data ratearchitecture to achieve high speed operation.
