DDR Memory Technologies: A System Designer Perspective
Memory is an integral part of any electronic system which influences product features, cost, performance and power. While non-volatile memory like FLASH, HDD etc define the system capacity to store data, volatile memory(SRAM, DRAM etc.) directly impact system performance. While SRAM mostly serve on-chip needs, DRAMs serve the majority of system memory requirements. Today, DRAM constitutes a significant part of the system BOM cost and the same is expected to grow in coming years.
The tutorial will cover an overview of various memory technologies including DDR (Double data rate) DRAM architecture, evolution and standards. A system designer perspective of choosing a memory technology like LPDDRX, DDRX and HBM as well as Platform implementations like DIMM, Memory down and POP options will be reviewed. Design considerations including Signal integrity and power integrity for today's high performance needs will be reviewed.
