1.0 Key Features
• VDD : 2.5V ± 0.2V, VDDQ : 2.5V ± 0.2V for DDR266, 333
• VDD : 2.6V ± 0.1V, VDDQ : 2.6V ± 0.1V for DDR400
• Double-data-rate architecture; two data transfers per clock cycle
• Bidirectional data strobe [DQS] (x4,x8) & [L(U)DQS] (x16)
• Four banks operation
• Differential clock inputs(CK and CK)
• DLL aligns DQ and DQS transition with CK transition

-. Burst length (2, 4, 8)
-. Burst type (sequential & interleave)
• All inputs except data & DM are sampled at the positive going edge of the system clock(CK)
• Data I/O transactions on both edges of data strobe
• Edge aligned data output, center aligned data input
• LDM,UDM for write masking only (x16)
• DM for write masking only (x4, x8)
• Auto & Self refresh
• 7.8us refresh interval(8K/64ms refresh)
• Maximum burst refresh cycle : 8
