Description

The power / ground line noise due to the parasitic inductances of package and PCB causes serious problems for realizing giga-bit scale and ultra-high bandwidth DRAMs. First, this paper proposes "Constant-Current Voltage-Down Converter" which requires constant current through external Vdd/Vss pins, resulting in the minimum di/dt. Second, this paper proposes "Partially Inverted Data Bus Architecture" which reduces simultaneous switching noise to (1/n) using only (n-1) bit flag signals, and realizes wide 128 or 256 bit I/Os at 1G Hz.
