PRN256M16V00HG8GNF-125 SPECTEK 256*16 BGA DDR3 全新原装

GENERAL DESCRIPTION 

The PRN256M16V00HG8GNF-125 is a high  performance dynamic random-access 4Gb device. These  components are organized in a x16 configuration, and  utilize 8 bank architecture with a synchronous DDR3  interface. These DDR3 SDRAM components use double  data rate architecture to achieve high speed operation.
