3.2
DDR mobile RAM device
The 512-Mbit DDR mobile RAM is organized as 8,388,608 × 16 bits × 4 banks. It achieves
low power consumption and high-speed data transfer using a 2-bit prefetch pipeline
architecture.
Command and address inputs are synchronized with the positive edge of the clock. Data
inputs and outputs are synchronized with both edges of DQS (data strobe). DLL is not
implemented.
The device architecture is illustrated in
Figure 5.
