Features

  • x32 organization
  • Double-data-rate architecture; two data transfers per clock cycle
  • The high-speed data transfer is realized by the 2 bits prefetch pipelined architecture
  • Bi-directional data strobe (DQS) is transmitted /received with data for capturing data at the receiver
  • Data inputs, outputs, and DM are synchronized with DQS
  • DQS is edge-aligned with data for READs; centeraligned with data for WRITEs
  • Differential clock inputs (CK and /CK)
  • DLL aligns DQ and DQS transitions with CK transitions
  • Commands entered on each positive CK edge; data and data mask referenced to both edges of DQS
  • Data mask (DM) for write data
