576Mb (x9, x18) Separate I/O RLDRAM^2 Memory

ADVANCED INFORMATION

JULY 2012

FEATURES



533MHz DDR operation (1.067 Gb/s/pin data

rate)



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



38.4 Gb/s peak bandwidth (x18 Separate I/O 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)



Data valid signal (QVLD)



8 internal banks

HSTL I/O (1.5V or 1.8V nominal)

25‐60Ω matched impedance outputs

2.5V V_EXT, 1.8V V_DD, 1.5V or 1.8V V_DDQI/O

On‐die termination (ODT) R_TT

IEEE 1149.1 compliant JTAG boundary scan

Operating temperature:

Commercial

(T_C= 0° to +95°C; T_A= 0°C to +70°C),

Industrial

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



(T_C= ‐40°C to +95°C; T_A= ‐40°C to +85°C)
