For such applications the use of multiple dual-inline memory modules (DIMMs) with multiple ranks enables timeefficient processing of high-volume data. However, the deterioration of the channel frequency response due to the presence of DIMM connectors and multiple ranks makes it challenging to perform low-power read and write (R/W) operations at high-speed. Recent works have demonstrated the use of near-ground signaling (NGS) for low-power operation and signal-integrity enhancement with the aid of transmit supply regulation [1,2]. In contrast to their differential nature,
