Consumer DRAM DDR is ideally suited for mainstream consumer applications. We
optionally offer products for industrial applications with Extended Temperature Range
(iTemp) indicated by an "I" in the product type (e.g. HY
I 25DC256800CF-6).
Double Data Rate (DDR) SDRAM is a further development of SDR products. Data of DDR SDRAMs are
read on both the rising and the falling edge of per clock cycle, thereby delivering twice the
bandwidth of standard SDR SDRAMs.
A DDR SDRAM clocked at 200 MHz has a burst rate of 400 Mbit/s or a peak bandwidth of more
than 3.2 Gbytes/s in a 8-byte application.
