• V
• V
• 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
• MRS cycle with address key programs
• 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
• 66pin TSOP II
•
