XDR DRAM

XDR DRAM is a high performance RAM Interface like SDR-SDRAM and DDR-SDRAM. The XDR solution was engineered to be effective in small high-bandwidth consumer systems as well as in high-performance main memory applications. Rambus owns the technology. XDR is the official choice by Sony for the Playstation 3 console.

Parameters

Performance:

  • Clock rate at 400 MHz (600, 800 and 1000 MHz planned)
  • 8 bits per clock and lane (ODR = Octal Data Rate) gives 3.2 GBit/s (4.8, 6.4 and 8 Gbit/s planned)
  • 8 or 16 lanes per chip gives 3.2 to 16 GByte/s
  • Features:

  • Bi-directional differential RSL (DRSL)
  • Programmable on-chip termination
  • Adaptive impedance matching
  • 8 bank memory architecture
  • Up to 4 Bank-interleaved transactions at full bandwidth
  • Point-to-point data interconnect
  • CSP packaging
  • Dynamic request scheduling
  • Early-read-after-write support for maximum efficiency
  • Zero overhead refresh
  • Low power:

  • 1.8V Vdd
  • Programmable ultra-low-voltage DRSL 200mV swing
  • Low-power PLL/DLL design
  • Power-down self-refresh support
  • Dynamic data width support with dynamic clock gating
  • Per pin I/O power-down
  • Sub-page activation support
  • Ease in system design:

  • Per bit FlexPhase circuits compensate to a 2.5 ps resolution
  • XDR Interconnect uses minimum pin count
  • Low latency

  • 1.25/2.0/2.5/3.33 ns request packets
