Seperate I/O RLDRAM 2 Memory
ADVANCED INFORMATION
SEPTEMBER 2014
FEATURES
 533MHz DDR operation (1.067 Gb/s/pin data rate)
 38.4Gb/s peak bandwidth (x18 at 533 MHz clock
frequency)
 Reduced cycle time (15ns at 533MHz)
 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.
 Differential input clocks (CK, CK#)
 Differential input data clocks (DKx, DKx#)
 On-die DLL generates CK edge-aligned data
and output data clock signals
 Data valid signal (QVLD)
 HSTL I/O (1.5V or 1.8V nominal)
 25-60Ω matched impedance outputs
 2.5V VEXT, 1.8V VDD, 1.5V or 1.8V VDDQ I/O
 On-die termination (ODT) RTT
 IEEE 1149.1 compliant JTAG boundary scan
 Operating temperature:
Commercial
(TC = 0° to +95°C)
