· Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this speci cation is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
· Storage Temperature is the case surface temperature on the center/top side of the DRAM. For the measurement conditions, please refer to JESD51-2 standard.




Description

 

The W3HG2128M72ACER is a 2x128Mx72 Double Data Rate DDR2 SDRAM high density module based on DDR2 SDRAM components. This memory module consists of eighteen stacks of 256Mx4 bit with 4 banks DDR2 Synchronous DRAMs in FBGA packages, mounted on a 240-pin DIMM FR4 substrate.
