A Single-Ended Parallel Transceiver With Four-Bit Four-Wire Four-Level Balanced Coding for the Point-to-Point DRAM Interface.

A four-bit four-wire four-level (4B4W4L) single-ended parallel transceiver for the point-to-point DRAM interface achieved a peak reduction of ~10 dB in the electromagnetic interference (EMI) H-field power, compared to a conventional 4-bit parallel binary transceiver with the same output driver power of transmitter (TX) and the same input voltage margin of receiver (RX). A four-level balanced codin...
