LATENCY (RLDRAM II)

MT49H16M18C

MT49H32M9C

Features

• 288Mb

• 400 MHz DDR operation (800 Mb/s/pin data rate)

• Organization

• 16 Meg x 18, 32 Meg x 9 Separate I/O

•8 banks

• Cyclic bank switching for maximum bandwidth

• Reduced cycle time (20ns at 400 MHz)

• Nonmultiplexed addresses (address multiplexing

option available)

• SRAM-type interface

• Read latency (RL), row cycle time, and burst

sequence length

• Balanced READ and WRITE latencies in order to

optimize data bus utilization

• Data mask for WRITE commands

• Differential input clocks (CK, CK#)

• Differential input data clocks (DKx, DKx#)

• On-chip DLL generates CK edge-aligned data and

output data clock signals

• Data valid signal (QVLD)

• 32ms refresh (8K refresh for each bank; 64k refresh

command must be issued in total each 32ms)

• 144-ball FBGA package

• HSTL I/O (1.5V or 1.8V nominal)

•25Ω–60Ω matched impedance outputs

• 2.5V VEXT, 1.8V VDD, 1.5V or 1.8V VDDQ I/O

• On-die termination (ODT) RTT
