WebDDR5 doubles the banks from 16 to 32. This allows for more pages to be open at a time, increasing efficiency. Also doubled is the minimum burst length to 16, up from 8 for DDR4. This improves data bus efficiency, providing twice the data on the bus, and consequently reduces the number of reads/writes to access the same cache data line.
