1.0  Key Features

• VDD : 2.5V ± 0.2V, VDDQ :  2.5V ± 0.2V for DDR**6, **3
• VDD : 2.6V ± 0.1V, VDDQ :  2.6V ± 0.1V for DDR**0
• Double-data-rate architecture; two data transfers per clock cycle
• Bidirectional data strobe [DQS] (x4,x8)  &  [L(U)DQS] (x*6)
• Four banks operation
• Differential clock s(CK and CK)
• DLL aligns  DQ and DQS transition with CK transition
• MRS cycle with address key programs
  -. Read latency : DDR**6(2, 2.5 Clock), DDR**3(2.5 Clock), DDR**0(3 Clock)    
  -. Burst length (2, 4, 8)
  -. Burst type (sequential & interleave)
• All s 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
• LDM,UDM for write masking only (x*6)
• DM for write masking only (x4, x8)
• Auto & Self refresh
• 7.8us refresh interval(8K/*4ms refresh)
• Maximum burst refresh cycle : 8
• *6pin TSOP II Pb-Free package
• RoHS compliant
