TL;DR: A 64-Mbit bidirectional data strobed, double-data-rate SDRAM achieves a peak bandwidth of 2.56 GByte/s on a 64-bit-channel, 256-MByte memory system at V/sub cc/=3.3 V and T=25/spl deg/C.

TL;DR: This work tackles challenges in GDDR5 such as clock jitter and signal integrity with respect to forwarded clocking, data training for write and read de-skewing, clock training, channel-error detection, bank group and data coding.

TL;DR: To realize the enhanced bank access flexibility, this DRAM employs the following techniques: skewed control logic, PVT variation compensated IO sense amplifier with auto calibration by replica impedance monitor, FIFO based BLSA enable signal generator, low latency VPP generator and active jitter canceller.

TL;DR: A channel crosstalk equalizer with programmable signal ordering capability for the DRAM transmitter is presented and tri-mode clocking is addressed to reduce the system jitter for better timing margin: PLL off, LC-PLL and injection-locked oscillator.

TL;DR: This 256 MB memory system achieves 256 Gb/s peak bandwidth with a 160 MHz clock and 64b channel using a /spl plusmn/0.4 V-swing, push-pull type I/O interface (SSTL).
