IS49NLS18320-25BLI 特徵

  • Differential input clocks (CK, CK#)
  • Differential input data clocks (DKx, DKx#)
  • On-die DLL generates CK edge-aligned data and 400MHz DDR operation (800Mb/s/pin data rate) 14.4 Gb/s peak bandwidth (x18 Separate I/O at 400 MHz clock frequency) DECEMBER 2012
  • Reduced cycle time (15ns at 400MHz)
  • 32ms refresh (16K refresh for each bank; 128K refresh command must be issued in total each 32ms) 8 internal banks
  • Non-multiplexed addresses (address multiplexing
  • option available) SRAM-type interface Programmable READ latency (RL), row cycle time, and burst sequence length
  • Balanced READ and WRITE latencies in order to optimize data bus utilization
  • Data mask signals (DM) to mask signal of WRITE data; DM is sampled on both edges of DK. output data clock signals
  • Data valid signal (QVLD)
  • HSTL I/O (1.5V or 1.8V nominal)
  • On-die termination (ODT) RTT
