Dynamic Random Access Memory (DRAM) Intelligent Memory Dynamic Random Access Memory (DRAM) includes a full range of JEDEC-compliant DRAMs and ECC DRAMs (SDRAM, DDR, DDR2, DDR3, DDR4, LPDDR4). From an application's point of view, these components work like a monolithic device. The DRAM devices allow for maximum levels of memory density without altering existing board layouts or designs.
