DDR Modules
DDR (Double Data Rate) SDRAM retroactively is also called DDR1 once it was superseded by DDR2. None of its successors are forward or backward-compatible with DDR1.
captures data at twice the clock frequency as SDR, creating high-speed, higher density and lower power memory modules. DDR operates at data rates from 200-400 Mb/s with a clock frequency of 100-200 MHz and operating voltages of 2,5/2,6V.
Standard speeds for DDR include PC-2100, PC-2700 and PC-3200. MEMPHIS DDR SDRAM Memory Modules are available in a variety of capacities, speeds, form factors and configurations for embedded systems and industrial applications.
We offer DDR modules from the following memory manufacturers:
