Ahead of the field, Elpida Memory is extensively promoting the development of XDR DRAM. The competitive edge gained by Elpida Memory's advanced technological and production capabilities enables us to take a leading share in the XDR market.
Features
Highest pin bandwidth
- 4.8/4.0/3.2Gbps Octal Data Rate (ODR) signaling
4.8/4.0/3.2GHz data rate, octuple the data transfer rate of 600/500/400MHz system clock - Bi-directional differential RSL (DRSL)
Flexible read / write bandwidth allocation
Minimum pin count - On-chip termination
Reduced system cost and routing complexity
Low power
- 1.8V(512Mb) / 1.5V(1Gb) VDD
- Small-swing I/O signaling (DRSL) (200mV)
- Power-down support
Highest sustained bandwidth per DRAM device
- 9.6GB/s (4.8E), 8.0GB/s (4.0D), 6.4GB/s (3.2A, 3.2B, 3.2C) peak data transfer rate
- 8 banks:
Bank-interleaved transactions at full bandwidth - Dynamic request scheduling
- Early-read-after-write support for maximum efficiency
- Zero overhead refresh
