Forterra, Inc. manufactures water and drainage pipe and products in the United States and Eastern Canada. It also manufactures structural and specialty precast products, and precast concrete bridge girders; and prestressed concrete, welded steel,â¦.
Called double data rate (or DDR), it let the memory transfer data on both the rising and falling edges of the clock signal, giving it the capability to move information nearly twice as quickly as with regular SDR SDRAM.
DDR operates at a voltage of 2.5 V, compared to 3.3 V for SDR SDRAM. The different pin configuration for DDR RAM Modules: 172-pin MicroDIMM, used for DDR SDRAM 184-pin DIMM, used for DDR SDRAM 200-pin SO-DIMM, used for DDR SDRAM and DDR2 SDRAM 204-pin SO-DIMM, used for DDR3 SDRAM 214-pin MicroDIMM, used for DDR2 SDRAM
