With data being transferred 64 bits at a time per memory module, DDR3 SDRAM gives a transfer rate of (memory clock rate) × 4 (for bus clock multiplier) × 2 (for data rate) × 64 (number of bits transferred) / 8 (number of bits in a byte). Thus with a memory clock frequency of 100 MHz, DDR3 SDRAM gives a maximum transfer rate of 6400 MB/s.
A DIMM (Dual In-Line Memory Module) is a popular type of memory module used in computers. It is a printed circuit board with one or both sides (front and back) holding DRAM chips and pins . [ 1 ] The vast majority of DIMMs are manufactured in compliance with JEDEC memory standards , although there are proprietary DIMMs.
The number of chip ID bits remains at three bits, allowing up to eight stacked chips (3 → 3). A third bank group bit (BG2) was added, allowing up to eight bank groups (2 → 3). The maximum number of banks per bank group remains at four (2 → 2), The number of row address bits remains at 17, for a maximum of 128K rows (17 → 17).
