A 128Mb multi port media DRAM with four independent 4Gb/s serial ports

This paper proposes a 128-Mb multimedia-specific DRAM having 4 independent 4Gbps serial ports, 16 independent banks, and 512b I/O bus. The core bandwidth of 51.2-Gbps is fully utilized by the four independent RX-TX 4-Gbps serial ports. The over-sampling clock/data recovery, boosted column select, and data-line redundancy schemes realize high-speed data path. It is fabricated using 1.8V, 0.10/spl mu/m standard DRAM technology.
