Advance Information

1M × 32 Bits × 4 Banks Double Data Rate Synchronous RAM

With Bi-Directional Data Strobe and DLL

General Overview

The NT5DS4M32EG is 134,217,728 bits of double data rate synchronous dynamic RAM organized as 4 x 1,048,576

bits by 32 I/Os. Synchronous features with Data Strobe allow extremely high performance up to 400Mbps/pin. I/O

transactions are possible on both edges of the clock. Range of operating frequencies, programmable burst length and

programmable latencies allow the device to be useful for a variety of high performance memory system applications.

Features

• VDD = 2.5V±5% , VDDQ = 2.5V±5%

• SSTL_2 compatible inputs/outputs

• 4 banks operation

• MRS cycle with address key programs

-CAS latency 2,3 (clock)

-Burst length (2, 4, 8 and Full page)

-Burst type (sequential & interleave)

• Full page burst length for sequential burst type

only

• Start address of the full page burst should be even

• All inputs except data & DM are sampled at the ris-

ing edge of the system clock

• Differential clock input(CK & /CK)

• Data I/O transaction on both edges of Data strobe

• 4 DQS (1 DQS/Byte)

• DLL aligns DQ and DQS transaction with Clock

transaction

• Edge aligned data & data strobe output

• Center aligned data & data strobe input

• DM for write masking only

•Auto & self refresh

• 32ms refresh period (4K cycle)

• 144-Ball FBGA package

• Maximum clock frequency up to 200MHz

• Maximum data rate up to 400Mbps/pin
