What will happen with 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
