Samsung has introduced yet another extension to the LPDDR5 specification at the International Solid-State Circuits Conference (ISSCC), increasing data transfer rates to 12,700 MT/s (12.7 GT/s). To increase the speed, Samsung had to add four-phase self-calibration and AC-coupled transceiver equalization to its DRAM chips, which it calls its LPDDR5-Ultra-Pro DRAM.
