The term rank was created and defined by JEDEC, the memory industry standards group. On a DDR, DDR2, or DDR3 memory module, each rank has a 64-bit-wide data bus (72 bits wide on DIMMs that support ECC). The number of physical DRAMs depends on their individual widths. For example, a rank of ×8 … Visualizza altro A memory rank is a set of DRAM chips connected to the same chip select, which are therefore accessed simultaneously. In practice all DRAM chips share all of the other command and control signals, and only the chip … Visualizza altro There are several effects to consider regarding memory performance in multi-rank configurations: • Multi-rank modules allow several open DRAM pages … Visualizza altro • Memory geometry Visualizza altro WebRank Subsetting •Instead of using all chips in a rank to read out 64-bit words every cycle, form smaller parallel ranks •Increases data transfer time; reduces the size of the row buffer •But, lower energy per row read and compatible with modern DRAM chips •Increases the number of banks and hence promotes parallelism (reduces queuing delays)
