Superior Quality and Reliability

Etron Technology’s complete line of specialty DRAM products include SDR, DDR, DDR2, DDR3, DDR4, and LPDDR2 SDRAM, which provide densities ranging from 16Mb to 8Gb and a number of I/O bits from 4 to 64 bits. DDR SDRAM, also called Double Data Rate Synchronous Dynamic Random Access Memory, differs from SDR (Single Data Rate) which can only be read and written once in a single cycle. DDR (Double Data Rate) means that a single cycle can be read or written two times. Under the condition that the core clock remains unchanged, the data transfer speed is doubled, so that the DDR SDRAM doubles the system clock and data can be transferred on both the rising and falling edges.
