Key Features

  • 1.8V power supply.
  • Double-data-rate architecture: two data transfers per clock cycle.
  • Bi-directional, differential data strobe (DQS and /DQS) is transmitted/received with data, to be used in capturing data at the receiver.
  • 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.
