WebThe Double Data Rate (DDR) memory interface for synchronous dynamic random-access memory (SDRAM) has been around since the mid-1990s with standards being released … WebDec 10, 2024 · For every 128 bits of data, DDR5 DRAMs has 8 additional bits for ECC storage. The DRAMs internally compute the ECC for the WR data and store the ECC code in the additional storage. On a read operation, the DRAMs read out both the actual data as well as the ECC code and can correct any single-bit error on any of the read data bits.
