Is a high performance HyperRAM controller really simpler than a normal DRAM controller? It's serial rather than parallel so you need higher frequency signals for the same bandwidth.
- thrtythreeforty 4y agoYes, significantly so. However you saturate the bus with less effort (lower frequency, less wires), so perhaps the simplicity is due to a lower theoretical performance.
- justsomehnguy 4y ago> First-generation HYPERRAM™ devices supported up to 166 MHz DDR clock frequency whereas as second- generation devices that now support a clock frequency of 200 MHz have a peak data transfer rate of 0.4 GBps. [0] 400MB/s for 8MB chip? Sounds enough for me.
